arm: Remove CAR_MIGRATE Kconfig and associated cruft

This is essentially a revert of commit 10bd772d. The CAR_MIGRATE
    mechanism is only useful to migrate variables from a special region
    (e.g. cache as RAM) into DRAM-backed CBMEM between different parts of
    the romstage (it does not persist into ramstage). Since ARM devices use
    SRAM for which there is no reason to become inaccessible in later parts
    of the romstage, this mechanism isn't useful for them. Removing it makes
    the romstage.ld script much simpler, which has the nice side-effect of
    putting the BSS at the end of the memory image (so that cbfstool can
    actually figure out that it doesn't need to be part of the ROM image).

console: Make cbmem depend on x86.

The cbmem implementation isn't supported on anything other than x86 right now
    and actually causes memory corruption on ARM machines. Until that's fixed, this
    will prevent people from turning it on and causing hard to track down errors.
