Kyösti Mälkki a7dd645594 CBMEM: Add config CBMEM_TOP_BACKUP ...

AGESA and binaryPI boards have no easy way to determine correct
cbmem_top() location early enough when GFXUMA is enabled, so they
will use these functions with EARLY_CBMEM_INIT as well.

At the end of AmdInitPost() the decisions of UMA base and size
have not been written to hardware yet. The decisions are stored
inside AGESA heap object we cannot locate from coreboot proper
until after AmdInitEnv().

Modify code such that weak backup functions are only defined
for LATE_CBMEM_INIT; they are somewhat troublesome to handle.
