ipq5018: Enable LZMA decompression support

Browse source 
LZMA usually performs better than gzip in terms of compression
ratio, IPQ5018 has small flash memory and hence the lzma support
is enabled defining the CONFIG_LZMA define.

help
If this option is set, support for LZMA compressed images
is included. The LZMA algorithm can run in-place as long as the
compressed image is loaded to the end of the output buffer, and
trades high compression ratios and fairly fast decompression speed.
