Add crypto compression alg for 842 hardware compression and decompression, using the alg name "842" and driver_name "842-nx". This uses only the PowerPC coprocessor hardware for 842 compression. It also uses the hardware for decompression, but if the hardware fails it will fall back to the 842 software decompression library, so that decompression never fails (for valid 842 compressed buffers). A header must be used in most cases, due to the hardware's restrictions on the buffers being specifically aligned and sized. Due to the header this driver adds, compressed buffers it creates cannot be directly passed to the 842 software library for decompression. However, compressed buffers created by the software 842 library can be passed to this driver for hardware 842 decompression (with the exception of buffers containing the "short data" template, as lib/842/842.h explains).
