drivers/intel/fsp2_0: Add preload_fspm and preload_fsps
In the non-XIP world, FSP is normally memmapped and then decompressed.
The AMD SPI DMA controller can actually read faster than mmap. So by
reading the contents into a buffer and then decompressing we reduce boot
time.
BUG=b:179699789
TEST=Boot guybrush and see 30ms reduction in boot time
