soc/intel/*: Allow configuring 8254 timer via CMOS

Currently, the `USE_LEGACY_8254_TIMER` Kconfig option is the only way
to enable or disable the legacy 8254 timer. Add the `legacy_8254_timer`
CMOS option to allow enabling and disabling the 8254 timer without
having to rebuild and reflash coreboot. If options are not enabled or
the option is missing in cmos.layout, the Kconfig setting is used.
