crypto: nx - reduce chattiness of platform drivers
While we never would successfully load on the wrong machine type, there
is extra output by default regardless of machine type.
For instance, on a PowerVM LPAR, we see the following:
nx_compress_powernv: loading
nx_compress_powernv: no coprocessors found
even though those coprocessors could never be found.
