crypto: hisilicon/zip - add lz4 algorithm for hisi_zip

Add the "hisi-lz4-acomp" algorithm by the crypto acomp. When the
8th bit of the capability register is 1, the lz4 algorithm will
register to crypto acomp, and the window length is configured to
16K by default.

Since the "hisi-lz4-acomp" currently only support compression
direction, decompression is completed by the soft lz4 algorithm.
