Get some build coverage of S5P/Exynos AES H/W acceleration driver.
Driver uses DMA and devm_ioremap_resource() so add DMA and IOMEM
dependencies for the compile testing.

Driver enabled runtime PM but did not revert this on removal. Re-binding
of a device triggered warning:

Add proper error path (for disabling runtime PM) when registering of
hwrng fails.

Changes since v1:
1. Call also pm_runtime_dont_use_autosuspend() to revert everything
In case of timeout during read operation, the exit path lacked PM
runtime put. This could lead to unbalanced runtime PM usage counter thus
leaving the device in an active state.
Fixes: d7fd6075a205 ("hwrng: exynos - Add timeout for waiting on init done")

The driver uses pm_runtime_put_noidle() after initialization so the
device might remain in active state if the core does not read from it
(the read callback contains regular runtime put). The put_noidle() was
chosen probably to avoid unneeded suspend and resume cycle after the
initialization.

Hello
I had some report of random data corruption of people using cryptsetup with my
sun4i-ss driver (via AF_ALG).
Even if it is hard to hit, I could confirm it by continuously moving files on a
LUKS encrypted FS and comparing hash of it before and after.
The corruption is always when decipherin
