Florian Fainelli 5dc49c75a2 decompressors: make the default XZ_DEC_* config match the selected architecture
Change the defautl XZ_DEC_* config symbol to match the configured
architecture.  It is perfectly legitimate to support multiple XZ BCJ
filters for different architectures (e.g.: to mount foreign squashfs/xz
compressed filesystems), it is however more natural not to select them all
by default, but only the one matching the configured architecture.

LZMA2 compression algorithm and BCJ filters are supported using
the .xz file format as the container. For integrity checking,
CRC32 is supported. See Documentation/xz.txt for more information.

This allows passing .xz files to the in-kernel XZ decoder via
a character special file. It calculates CRC32 of the decompressed
data and writes diagnostics to the system log.
Unless you are developing the XZ decoder, you don't need this
and should say N.
