cpu/amd/fam10h-15h: Fix BSP stack corruption on 32-core Fam10 systems
On some multi-socket AMD platforms there are too many cores for all
APs to start up without stack collisions with either each other or
the BSP. On such platforms a larger amount of CAR memory is also
available.
Allow the maximum DCACHE size to be increased via a mainboard-
specific Kconfig flag.
