Ever since commit a28aad66 ("firmware: coreboot: Collapse platform
drivers into bus core") the Kconfig entries GOOGLE_COREBOOT_TABLE_OF
and GOOGLE_COREBOOT_TABLE_ACPI have been dead. They have no "help"
text and thus aren't user choosable. They also aren't "select"ed by
anything. They also control the compilation of no code.

Let's remove them.
