src/Kconfig: add MAINBOARD_NEEDS_CMOS_OPTIONS

Browse source 
The addition provides a way to select USE_OPTION_TABLE for a mainboard
which depends on the CMOS backend for options.  This is needed to
support update mechanism based on Top Swap that permits recovery via a
CMOS reset (see [0]).  The indirection is necessary because
USE_OPTION_TABLE is part of a `choice`.
