mb/siemens/chili: Rework Kconfig

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

Built chili/base with BUILD_TIMELESS=1, coreboot.rom remains the same.
