mb/intel/kblrvp: Rework Kconfig

Rework Kconfig file that each variant has its own config option with
their specific selects / configuration and move common selects to
`BOARD_INTEL_KBLRVP_COMMON`, which is used as base for each
variant.

Built each variant with `BUILD_TIMELESS=1` and all generated
coreboot.rom files remain identical. Excluded the .config file by
disabling `INCLUDE_CONFIG_FILE` to make this reproducible.
