Julius Werner d84afd3e61 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.
