Kconfig: Add option to compress ramstage with LZ4
When ramstage is loaded asynchronously, as on the skyrim boards, the
faster decompression of LZ4 allows for faster boot times than the
tighter compression of LZMA.
To make this change, the name of the existing ramstage_compression
option needs to be updated.
