soc/amd/picasso: Enable cache in bootblock

Unlike prior AMD programs, picasso cannot rely on the cache-as-RAM
setup code to properly enable MTRRs.  Add that capability to the
bootblock_c_entry() function.  In addition, enable an MTRR to cache
(WP) the flash boot device and another for WB of the non-XIP bootblock
running in DRAM.
