mb/google/sarien: Remove DRIVERS_PS2_KEYBOARD In order to prevent keyboard keys pressed at boot from causing issues in the payload remove the PS2 keyboard driver so it does not get initialized until it is needed in libpayload. This was enabled initially because the keyboard controller on this platform does not come up in translated mode, so unless coreboot called keyboard_init() the keyboard would never work properly in the kernel because it would come up as an "AT Raw" device instead of an "AT Translated" device. Instead of initializing the keyboard in coreboot a workaround is added to the payload to put the keyboard into translated mode. BUG=b:126633269 TEST=boot on sarien while pressing keys and ensure libpayload and/or the kernel does not have any issues initializing the keyboard.

coreboot is a Free Software project aimed at replacing the proprietary BIOS (firmware) found in most computers. coreboot performs a little bit of hardware initialization and then executes additional boot logic, called a payload.
With the separation of hardware initialization and later boot logic, coreboot can scale from specialized applications that run directly firmware, run operating systems in flash, load custom bootloaders, or implement firmware standards, like PC BIOS services or UEFI. This allows for systems to only include the features necessary in the target application, reducing the amount of code and flash space required.
coreboot was formerly known as LinuxBIOS.
After the basic initialization of the hardware has been performed, any desired "payload" can be started by coreboot.
See https://www.coreboot.org/Payloads for a list of supported payloads.
coreboot supports a wide range of chipsets, devices, and mainboards.
For details please consult:
ANY_TOOLCHAINKconfig option if you're feeling lucky (no support in this case).
Please consult https://www.coreboot.org/Build_HOWTO for details.
If you want to test coreboot without any risks before you really decide to use it on your hardware, you can use the QEMU system emulator to run coreboot virtually in QEMU.
Please see https://www.coreboot.org/QEMU for details.
