drivers/intel/fsp2_0: add option to compress FSP-M in cbfs
Allow the ability for chipset or mainboard to choose to
compress FSP-M in cbfs using LZMA or LZ4 routines. However, only
non-XIP platforms will support FSP-M compression. Since the main
cbfs decompression paths are utilized add the appropriate checks
for including compression algorithms under the FSP-M compression
options.
On picasso FSP-M (debug builds) the following savings were measured:
no-compression:
fspm.bin 720896 none
FSP_COMPRESS_FSP_M_LZ4:
fspm.bin 138379 LZ4 (720896 decompressed) -80%
FSP_COMPRESS_FSP_M_LZMA:
fspm.bin 98921 LZMA (720896 decompressed) -86%
