This patch clears the typematic buffer when disabling keyboard scan.
When the device goes to tablet mode with a key being pressed, this
should prevent keyboard_protocol_task from sending scan codes to the
host.

This adds new key combination (Left_Shift+Esc+Refresh+Power) that triggers
recovery mode by setting a new host event
EC_HOST_EVENT_KEYBOARD_RECOVERY_HW_REINIT. This host event can be used
whenever user wants to request entry into recovery mode by
reinitializing all the hardware state (e.g. memory retraining).

Refactored keyboard scan enable/disable flag such that it is a mask of
potential disable sources. When all disable sources are off, scanning is
enabled, otherwise scanning is disabled. This fixes a recently introduced
bug in which enabling/disabling keyboard scanning due to lid angle in S3
was interfering with enabling/disabling keyboard scanning due to power
button. This also allows for easy expansion for future causes for disabling
keyboard scanning.

TEST=Manual tests with a glimmer. Used the ksstate console command to
check state of keyboard scanning under all permutations of power button

Added ability to disable the keyboard to wake from suspend when the lid
is outside a certain angle range. This has been added to glimmer by
defining CONFIG_LID_ANGLE_KEY_SCAN in its board.h.
Also modified the lid angle calculation to include a reliability
flag which can be used to tell when the hinge aligns too closely
with gravity and the lid angle value is unreliable.
BUG=none
BRANCH=rambi
TEST=Tested on a glimmer:
In S3, verified that when the lid is open past ~180 deg, the keyboard
does not wake the machine. Also verified that if you align hinge with
gravity, the keyboard enabled/disabled status remains the same (since
we can't actually trust the lid angle value).

Scanning is now performed identically on all platforms. keyboard_scan

keyboard protocol on the top end.
8042 can now take advantage of CONFIG_KEYBOARD_TEST to simulate scan results.

This is part one of a series to merge the keyboard scan interface to
be common across all platforms.
This change just moves and renames files and APIs and removes some
read code, and sets up protocol-specific CONFIG options. It makes the
next CL which actually merges keyboard scanning easier to parse.

Provide the required plumbing for the stm32 keyboard scan code so that
the message layer will pick up keyboard scans.
The design is as follows:
- When a change in keyboard state is detected, the keyboard matrix
scanning code will call the board-specific board_keyboard_scan_ready()
function to interrupt the AP.
- The AP will initiate a CMDC_KEY_STATE transaction over SPI or I2C
- The SPI or I2C driver will call message_process_cmd() to process the
command
- This in turn will call keyboard_get_scan() to get the latest scan data
For SPI:
- The AP will initiate an 20-byte (or longer) SPI transaction
- The EC will see the command, and provide the keyboard state in response,
with the response being part of the same transaction
For I2C:
- The AP will initiate a 1-byte write to set the EC mode.
- The AP will then initiate an 18-byte read, and the EC will send the
message including keyboard state
