option: Introduce CMOS_LAYOUT_FILE Kconfig symbol

Browse Source 
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.
