Majority of the chipsets do not have a dedicated GPIO to trigger
AP cold reset. Current code either ignores cold reset or does a warm
reset instead or have a work around to put AP in S5 and then bring
back to S0. In order to avoid the confusion, removed the cold reset
logic and only apreset is used hence forth.

Since pretty much always, we've declared console commands to take
a "longhelp" argument with detailed explanations of what the
command does. But since almost as long, we've never actually used
that argument for anything - we just silently throw it away in
the macro. There's only one command (usbchargemode) that even
thinks it defines that argument.
We're never going to use this, let's just get rid of it.

In http://crosreview.com/28402 code was added to power/gaia.c that
disabled keyboard scanning if the power button was pressed. The
purpose, according to that change, was to prevent accidental reboots by
pressing the power button together with another key that wasn't the
"Refresh" key (specifically: LCtrl, Tab, Reload, t, [, ], y, Dim Screen
and Mute).
At the time the original code was added, there was already code in the
power button interrupt handler to accomplish the same purpose: see
commit 29d25d807c18 ("Keyboard scan must stop driving columns when power
button is pressed."). It's unclear if the code in the interrupt handler
didn't work or if there was some other bug with it. ...or if perhaps
the changes in "gaia/power.c" weren't actually needed and the important
part of the original change was the mutex added to the scanning task.
In any case, current testing indicates that the code in power/gaia.c,
power/rockchip.c, and power/tegra.c isn't needed anymore. I ran through
the test sequence described in the original CL on my veyron_jerry and I
don't see any accidental reboots.
It's also instructive to note that only ARM boards (all presumably
copied from gaia) have this extra code. Presumably if the code was
actually needed then x86 boards would also need it.
In any case, let's remove it. It's suspected that there's some crazy
race where the disable in power/rockchip.c is overriding the enable in
the main power key handling code and leaving the keyboard disabled.

The debounce timer might be too slow to actually update the state of
debounced_power_pressed by the time we do power_button_is_pressed in the S3->S5

here and make sure there are no deferreds active.

Alex did the reset workaround in power_on function.

workaround.
BUG=chrome-os-partner:35976

TEST=The BUCK1_ON_VSEL register default value is 0x18, and coreboot and
kernel will change this register to other value, but never set 0x18 to

check whether the RK808 reset to default after cold reboot. With this
patch, the value always reset to 0x18. I have test on jerry, mighty,

POWER_GOOD too early, note that it's on and move to the wrong state:

There was a way to brick the PMIC by programming its registers with a bad
configuration, this could prevent the AP from powering up properly (thus not
being able to unbrick it). The PMIC retains register state through S5 (presumably
due to RTC business) and they do not get reset at bootup unless the OTP reset is
asserted.
The OTP reset actually has to be asserted in a special(rather long as well)
sequence.
A bug was discovered while making this change(crosbug.com/p/31635): usleep does
not work for long delays. Since I needed at least 300ms on one of the delays I
used a workaround with a loop.
I also cleaned up some old tegra stuff and renamed things to be more semantic.
BUG=None
BRANCH=None
TEST=From the AP set a PMIC register from the default value of 0x7d to 0xfd:
user@ap~$ modprobe i2c-dev
user@ap~$ i2cget -f -y 0 0x1b 0x24
Check what the default state is, mine was 0x7d
user@ap~$ i2cset -f -y 0 0x1b 0x24 0xfd #or change 0xfd to something!=default
Cold reboot the dut("apreset" or "power on\npower off" will work) then check if
the PMIC registers got reset:
user@ap~$ modprobe i2c-dev
user@ap~$ i2cget -f -y 0 0x1b 0x24
0x7d(or whatever your default state was) #good
0xfd #bad, did not reset properly
Using "user@ap~$ i2cset -f -y 0 0x1b 0x24 0x00" instead will prove the bricking
of the PMIC/AP.

Seems that we were driving GPIO_PMIC_PWRON_H backwards. The only reason it
worked before is because of a stale feature from tegra which pretty much kept it
always disabled(enabled in our case due to _L).
Also removed old power signals and renamed signals so they're more semantic and
respect convention(no _H).

system off and 1 when system is on. The system will also use 8mA less now
(no more current leak into the PMIC).
