[coreboot] [PATCH] v3: print current and wanted LZMA scratchpad size

[Carl-Daniel Hailfinger]

Print current and wanted LZMA scratchpad size in the decompression
routine. That allows people to either adjust compression parameters
or scratchpad size.
Having a similar check during build time would be nice.
