Change in coreboot[master]: option: Introduce `CMOS_LAYOUT_FILE` Kconfig symbol

[Patrick Georgi (Code Review)]

Patrick Georgi has submitted this change. ( https://review.coreboot.org/c/coreboot/+/54366 )

Change subject: option: Introduce `CMOS_LAYOUT_FILE` Kconfig symbol
......................................................................

option: Introduce `CMOS_LAYOUT_FILE` Kconfig symbol

Mainboards with variants may not always use the same cmos.layout file.
Turn the hardcoded path into a Kconfig symbol to allow changing it.

Tested with BUILD_TIMELESS=1: Without including the config file in the
coreboot.rom and with `USE_OPTION_TABLE` selected, building for the Asus
P8H61-M PRO produces an identical coreboot image.
