[BNX2]: factor out gzip unpacker
This patch modifies gzip unpacking code in bnx2 driver so that it does not depend on bnx2 internals. I will move this code out of the driver and into zlib in follow-on patch. It can be useful in other drivers which need to store firmwares or any other relatively big binary blobs - fonts, cursor bitmaps, whatever. Patch is run tested by Michael Chan (driver author).
