"ibm, power9-nx" should be "ibm,power9-nx" and the mismatch was
causing nuisance errors at boot.

A few places (mostly old code) were using:
add_property_cells(hi32(number), lo32(number));
This patch converts them to use the helper rather than doing it manually.

Add NX config register values for P7+. Remove "P8" from all register
defines, where the define is common to P7+ and P8. For values new to P8
(specifically 842 prefeching), only enable on P8.
This should correctly setup the NX coprocessors on P7+ systems.

Add support for the 842 hw memory compression engine in the NX Coprocessor.
This moves the existing RNG support into its own nx-rng.c file, adds 842
support in a nx-842.c file, and creates a nx-crypto.c file to configure and
disable the crypto engines (which are not supported yet).
New nodes are created for each 842 engine found. This does not actually
process any of the data or drive the 842 engines, it only configures
registers to set up and enable/disable the engines appropriately, and
creates new nodes so the OS can drive the 842 engines.
