vc/amd/stoneyridge: Add definition for AGESA heap rebase

AgesaHeapRebase is an optional callout that allows AGESA to use a
coreboot-managed heap base address.  Its internal default location
is determined by AMD_HEAP_START_ADDRESS which is defined as 4 MB.

Add a #define that AGESA may use once the feature is available.
