soc/amd/picasso: Enable FSP compression
This change enables LZMA compression for both FSP-M and FSP-S. This
results in significant savings in the FSP size in each CBFS:
cbfstool firmware/image-trembyle.bin print -r COREBOOT | grep fsp
fspm.bin 0x9cdc0 fsp 132404 LZMA
(720896 decompressed)
fsps.bin 0xbdfc0 fsp 86146 LZMA
(327680 decompressed)
LZ4 works too, but the savings are smaller as compared to LZMA:
cbfstool firmware/image-trembyle.bin print -r COREBOOT | grep fsp
fspm.bin 0x9cdc0 fsp 189530 LZ4
(720896 decompressed)
fsps.bin 0xcbfc0 fsp 118952 LZ4
(327680 decompressed)
BUG=b:155322763,b:150746858,b:152909132
TEST=Verified that Trembyle boots to OS. No FSP-M or FSP-S errors in
boot logs.
