mb/google/brya: Rework BOARD_GOOGLE_BASEBOARD_* Kconfig

Current mainboard code supports different baseboard binding
example: brya uses BOARD_GOOGLE_BASEBOARD_BRYA and brask uses
BOARD_GOOGLE_BASEBOARD_BRASK Kconfig.

This patch makes the `BOARD_GOOGLE_BRYA_COMMON` Kconfig default
`n` and specific baseboard binding Kconfig can select this Kconfig.

It would also avoid adding if clause for specific baseboard binding
Kconfig everytime with introduction of newer mainboard in future.

TEST=Verified CONFIG_BOARD_GOOGLE_BRYA_COMMON=y while building brya
and brya coreboot.rom remains the same.
