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.
