soc/intel/jasperlake: Enable FSP-S compression
Use LZ4 compression technique to compress FSP-S. This provides some
SPI ROM space savings(~60 KiB) in each CBFS. FSP-M is XIP and hence not
compressed. LZ4 is chosen over LZMA since the decompression saves
~50 ms for an extra overhead of ~1.5 KiB.
LZ4 Compression:
fsps.bin 0xa9fc0 fsp 203423 LZ4 (262144 decompressed)
LZ4 Decompression:
17:starting LZ4 decompress (ignore for x86) 433,550 (1,154)
18:finished LZ4 decompress (ignore for x86) 461,620 (28,069)
LZMA Compression:
fsps.bin 0xa9fc0 fsp 202132 LZMA (262144 decompressed)
LZMA Decompression:
15:starting LZMA decompress (ignore for x86) 478,448 (1,174)
16:finished LZMA decompress (ignore for x86) 557,725 (79,277)
