This is tidier than every board defining its own module_id enum, and
encourages standard naming of modules.
A subsequent CL will do more cleanup (standardizing on MODULE_LED
instead of MODULE_POWER_LED and MODULE_LED_KIRBY), but it's easier to
do that as a separate CL than part of this one.

Originally, the ARM boards printed the keyboard scan matrix whenever
it changed. This generated a lot of output, so we filtered that at
the console channel level. When we refactored the keyboard scan
module, that changed so that the scan matrix was not printed by
default, and the 'ksstate' debug command was used to enable printing
it. But on ARM boards, 'ksstate on' wouldn't do anything without ALSO
using 'chan -1' to turn the keyboard console channel back on. And
without the scan matrix printing by default, there's no reason to keep
the keyboard channel off by default.

Changed ADC clock gating to disable the ADC module to conserve power,
and only enable it when needed. This saves about 15% of the power
consumed by the EC when the AP is running.
BUG=none
BRANCH=none
TEST=Run the ADC stress test. This runs 2000 consecutive ADC
reads of all the channels and verifies that the ADC module
successfully records the samples. Note that when running this
test make sure all other calls to read an ADC channel are
disabled because the ADC read function does not protect
against different tasks accesses.

The common/ subdir was getting cluttered. Move drivers for external

chipset_*.c to a new power/ directory.
This does not move/rename header files or CONFIG options. That will
be done in subsequent steps, since moving and modifying .c files in
the same CL is harder to review.

There is an analog temperature line on the Samus battery connector. We don't
yet know what it means, but there's a pull-up on it, so if it's reading
close to ADC_READ_MAX, we can probably assume there's no battery.
This change says that any reading within 90% of ADC_READ_MAX means the
battery pack is not present, so we can go ahead and boot without trying to
wake it up first.

Falco has shipped, so those numbers are evidently good enough.
Slippy is not being developed and won't be fixed. Simply note that
numbers are estimates.

Changed the low power idle task to use the low speed clock in deep
sleep. The low power idle task is currently only enabled for Peppy,
Slippy, and Falco. This change decreases power consumption when
the AP is not running.
Note that the low speed clock is slow enough that the JTAG cannot be
used and the EC console UART cannot be used. To work around that,
this commit detects when the JTAG is in use and when the EC console
is in use, and will not use the low speed clock if either is in use.
The JTAG in use never clears after being set and the console in use
clears after a fixed timeout period.
BUG=None
BRANCH=None
TEST=Passes all unit tests.
Tested that the EC console works when in deep sleep.
Tested that it is possible to run flash_ec when in deep sleep and
using the low speed clock.

Every chipset had its own header file just to declare a GPIO interrupt
handler. Since this seems to be a common feature of the power
interface, make a standard power_interrupt() API provided by
chipset.h. This lets us get rid of 4 include files, and makes it
easier to add more chipsets in the future.

On many of the Haswell boards, RCIN# was attached to PL6, which is not
an open-drain capable GPIO. As a workaround, we toggle it to an input
to get it into a high-Z state. Now that we understand the problem,
document it and remove the FIXME tag from the comments.
Baytrail systems map RCIN# to a different pin, so don't need this
workaround at all.

The backlight controller EEPROM is not enabling PWM mode and
it is reloaded every time the backlight state is changed.
Since we no longer have signals indicating when the PCH is
enabling or disabling backlight this hack will read the
controller every second at runtime to determine if it needs
to enable PWM mode.
This should be removed with the next build when the EEPROM is
changed to enable PWM mode by default.

These were the changes from bringup to get the first boards
booting successfully.
Mostly minor stuff, some may not be entirely correct still.
- disable internal clkrun so it behaves the same as other
boards, this can be experiemented with later but is too much
extra change during bringup
- enable 1.8V internal pullup since it is missing external
- wait for 1.5V and 1.2V PGOOD to ensure 5V rail is up
- turn on 3.3V DSW rail in S5, it can be disabled later at
runtime in theory but it is required for booting
- turn on USB in S3
- specific wireless bringup sequencing, WLAN power should
be first but the generic wireless function does it in the
other order.

The new boards will be populated with STM32L100RBT6,
so let's update the CHIP_VARIANT accordingly.
This is backward-compatible with the STM32L151RBT6 which is soldered on
older boards (it just doesn't use the full memory).

stm32l100 is mostly identical to stm32l151,
excepted that the RAM is smaller (10kB instead of 16kB for the RB SKU),
the EEPROM is smaller, there is no touch capability (but we are not
using those 2 features).
So, in the new stm32l100 variant configuration, we adjust the memory
size to 10kB and keep the regular UART RX buffer size (512 B) rather
than putting a 2kB buffer to fit in the new constraints.
