Manual unregistration and some remove functions can be
removed now.

Pull crypto updates from Herbert Xu:
"Here is the crypto update for 3.15:
- Added 3DES driver for OMAP4/AM43xx
- Added AVX2 acceleration for SHA
- Added hash-only AEAD algorithms in caam
- Removed tegra driver as it is not functioning and the hardware is
too slow
- Allow blkcipher walks over AEAD (needed for ARM)
- Fixed unprotected FPU/SSE access in ghash-clmulni-intel
- Fixed highmem crash in omap-sham
- Add (zero entropy) randomness when initialising hardware RNGs
- Fixed unaligned ahash comletion functions
- Added soft module depedency for crc32c for initrds that use crc32c"

None of these files are actually using any __init type directives
and hence don't need to include <linux/init.h>. Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.

The Nomadik HW RNG driver has seen some rust and is not preparing
the clock before use. Fix this up so we get rid of runtime
complaints from the clock subsystem.

For simple modules that contain a single amba_driver without any
additional setup code then ends up being a block of duplicated
boilerplate. This patch adds a new macro, module_amba_driver(),
which replaces the module_init()/module_exit() registrations with
template functions.

Jump to the end of the function for the clk_disable and clk_put rather than
returning directly.
A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)
// <smpl>
@r exists@
expression e1,e2;
statement S;
@@
e1 = clk_get@p1(...);
... when != e1 = e2
when != clk_put(e1)
when any
if (...) { ... when != clk_put(e1)
when != if (...) { ... clk_put(e1) ... }
* return@p3 ...;
} else S

The hardware random number generator by ST is used in both the Nomadik
8815 SoC and the U8500. It returns 16 bits every 400ns with automatic
delay if a read is issued too early. It depends on PLAT_NOMADIK.
