Mahipal Challa 640035a2dc crypto: zip - Add ThunderX ZIP driver core
Add a driver for the ZIP engine found on Cavium ThunderX SOCs.
The ZIP engine supports hardware accelerated compression and
decompression. It includes 2 independent ZIP cores and supports:

- DEFLATE compression and decompression (RFC 1951)
- LZS compression and decompression (RFC 2395 and ANSI X3.241-1994)
- ADLER32 and CRC32 checksums for ZLIB (RFC 1950) and GZIP (RFC 1952)

The ZIP engine is presented as a PCI device. It supports DMA and
scatter-gather.
