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.
