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.
