soc/amd/picasso: Enable cache in bootblock
Unlike prior AMD devices, 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.
BUG=b:147042464
TEST=Boot trembyle to payload and make sure bootblock isn't abnormally
slow.
