crypto: nx - Remove virt_to_abs() usage in nx-842.c
virt_to_abs() is just a wrapper around __pa(), use __pa() directly.
We should be including <asm/page.h> to get __pa(). abs_addr.h will be
removed shortly so drop that.
We were getting of.h via abs_addr.h so we need to include that directly.
Having done all that, clean up the ordering of the includes.
