powerpc/crypto: add 842 crypto driver
This patch add the 842 cryptographic API driver that submits compression requests to the 842 hardware compression accelerator driver (nx-compress). If the hardware accelerator goes offline for any reason (dynamic disable, migration, etc...), this driver will use LZO as a software failover for all future compression requests. For decompression requests, the 842 hardware driver contains a software implementation of the 842 decompressor to support the decompression of data that was compressed before the accelerator went offline.
