NX: Organize NX compression code to include 842 and gzip support
P9 NX also supports gzip compression. So this patch creates
nx-compress.c and reorg nx-842.c code so that common functions that are
needed for both 842 and gzip compression will be moved in to
nx-compress.c. This patch does not change the actual functionality.
