When the nx driver was pulled, the Makefile that actually
builds it is arch/powerpc/Makefile. This is unnatural.

This patch moves the line that builds the nx driver from
arch/powerpc/Makefile to drivers/crypto/Makefile where it
belongs.

The CRC peripheral is a hardware block used to compute the CRC of the block
of data. This is based on a CRC32 engine which computes the CRC value of 32b
data words presented to it. For data words of < 32b in size, this driver
pack 0 automatically into 32b data units. This driver implements the async
hash crypto framework API.

Add support for auto-loading of crypto drivers based on cpuid features.
This enables auto-loading of the VIA and Intel specific drivers
for AES, hashing and CRCs.

Requires the earlier infrastructure patch to add x86 modinfo.
I kept it all in a single patch for now.

I dropped the printks when the driver cpuid doesn't match (imho
drivers never should print anything in such a case)

One drawback is that udev doesn't know if the drivers are used or not,
so they will be unconditionally loaded at boot up. That's better
than not loading them at all, like it often happens.
