Kconfig: Get rid of obsolete symbols

CAR_MIGRATION was removed in commit:
cbf5bdfe - CBMEM: Always select CAR_MIGRATION

ALT_CBFS_LOAD_PAYLOAD was removed in commit:
cf6c9cc2 - Kill ALT_CBFS_LOAD_PAYLOAD

MARK_GRAPHICS_MEM_WRCOMB was removed in commit:
30fe6120 - MTRR: Mark all prefetchable resources as WRCOMB.

EXTERNAL_MRC_BLOB was removed in commit:
0aede118 - Drop unused EXTERNAL_MRC_BLOB

CACHE_ROM is only in Google's codebase.
LID_SWITCH is only in Google's codebase.
DEFAULT_POST_DEVICE_LPC is only in Sage's codebase.
ROMSTAGE_RTC_INIT is only in Sage's codebase, or was never used.

HUDSON_NOT_LEGACY_FREE never existed as far as I can tell.
MAINBOARD_DO_EDID never existed as far as I can tell.
