Add support for XZ decompression algorithm.

XZ (aka LZMA2) is the new version of lzma compression format.
The following patch add a cut-down version of XZ Embedded library (v20100702)
that supports only single-call API.

In order to enable XZ support, the CONFIG_XZ must be defined by board
configuration file.

For any details, please refer to XZ Embedded homesite
