[U-Boot] [PATCH v2 3/3] common/cmd_ximg.c: add ifdef protection for gzip uncompression

[Matthew McClintock]

Print a message if we do not have the ability to uncompress a gzip
image. Before, u-boot would just assume the routines were available

v2: If gzip is not available block out case statement and let it fall through
    to the default case
