soc/intel/skylake: Enable compression on FSP-S
Use LZ4 algorithm to compress FSP-S. This saves ~40 KiB and reduces the
boot time by ~7 ms. LZMA would save a further ~1 KiB, but adds ~9 ms to
the boot time.
LZMA size:
fsps_lzma.bin 0xb0dc0 fsp 146578 LZMA (188416 decompressed)
LZMA decompression time:
15:starting LZMA decompress (ignore for x86) 388,716 (47,646)
16:finished LZMA decompress (ignore for x86) 406,167 (17,450)
LZ4 size:
fsps_lz4.bin 0x242dc0 fsp 147442 LZ4 (188416 decompressed)
LZ4 decompression time:
17:starting LZ4 decompress (ignore for x86) 384,736 (47,864)
18:finished LZ4 decompress (ignore for x86) 384,796 (59)
