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

The SCI pin is not connected to a GPIO and it uses a different
method to trigger a pulse via LPC0SCI.
The ACPI specification requires SCI for 3 conditions:
- SCI event pending
- Input Buffer Empty
- Output Buffer Full
The buffer full/empty SCIs are used to nudge the kernel driver
along so it does not have to poll for a potential slow EC to
be ready. This only really makes sense for the kernel channel
so they are only generated there.
BUG=chrome-os-partner:8277
TEST=using (unreleased) coreboot BIOS to test that the kernel
can receive SCI events and the ACPI method is successfully run.

I don't have a system that has both an EC and a lightsaber, so I can't be
certain this works, but I *think* it will.
I do have a Link proto 0.5. With that, you can say
ectool lightbar test
and the EC console says it's poking at the lightbar, but of course there's
nothing there. If there was, it *should* flash in pretty colors. I have a
lightsaber attached to a BDS, and from the EC console running "lightsaber
test" does make it blink.
