The driver uses a couple of buffers that seem to
be __be32 or __be64 fields, but declares them as
u32. This means there are a number of warnings
from sparse due to casting to/from __beXXX.

Fix these by changing the types of the buffer
and the associated variables.

Convert the glue code for the PowerPC SPE implementations of AES-ECB,
AES-CBC, AES-CTR, and AES-XTS from the deprecated "blkcipher" API to the
"skcipher" API.  This is needed in order for the blkcipher API to be
removed.

Tested with:

	export ARCH=powerpc CROSS_COMPILE=powerpc-linux-gnu-
	make mpc85xx_defconfig
	cat >> .config << EOF
	# CONFIG_MODULES is not set
	# CONFIG_CRYPTO_MANAGER_DISABLE_TESTS is not set
	CONFIG_DEBUG_KERNEL=y
	CONFIG_CRYPTO_MANAGER_EXTRA_TESTS=y
	CONFIG_CRYPTO_AES=y
	CONFIG_CRYPTO_CBC=y

	EOF
	make olddefconfig
	make -j32
	qemu-system-ppc -M mpc8544ds -cpu e500 -nographic \
		-kernel arch/powerpc/boot/zImage \
		-append cryptomgr.fuzz_iterations=1000

Note that xts-ppc-spe still fails the comparison tests due to the lack
of ciphertext stealing support.  This is not addressed by this patch.

This patch also cleans up the code by making ->encrypt() and ->decrypt()
call a common function for each of ECB, CBC, and XTS, and by using a
clearer way to compute the length to process at each step.

data rate which takes approx. 700us to produce 16 bytes of output data
as per testing results. So configure the timeout as 1000us to also take
account of lack of udelay()'s reliability.

Commit daae28de has moved add_early_randomness() out of the
rng_mutex and tries to protect the reference of the new rng device
by incrementing the reference counter.

But in hwrng_register(), the function can be called with a new device
that is not set as the current_rng device and the reference has not been
initialized. This patch fixes the problem by not using the reference
counter when the device is not the current one: the reference counter
is only meaningful in the case of the current rng device and a device
is not used if it is not the current one (except in hwrng_register())

The problem has been reported by Marek Szyprowski on ARM 32bit

The NX crypto driver is using 'struct blkcipher_desc' to pass the IV
around, even for AEADs (for which it creates the struct on the stack).
This is not appropriate since this structure is part of the "blkcipher"

Just pass around the IV directly instead.
