Some registers like SECVID, CHAVID, CHA Revision Number,
CTPR were defined as 64 bit resgisters.  The IP provides
a DWT bit(Double word Transpose) to transpose the two words when
a double word register is accessed. However setting this bit
would also affect the operation of job descriptors as well as
other registers which are truly double word in nature.
So, for the IP to work correctly on big-endian as well as
little-endian SoC's, change is required to access all 32 bit
registers as 32 bit quantities.

This patch moves data allocated using kzalloc to managed data allocated
using devm_kzalloc and cleans now unnecessary kfrees in probe and remove
functions.  Also, linux/device.h is added to make sure the devm_*()
routine declarations are unambiguously available. Earlier, in the probe
function ctrlpriv was leaked on the failure of ctrl = of_iomap(nprop, 0);
as well as on the failure of ctrlpriv->jrpdev = kzalloc(...); . These
two bugs have been fixed by the patch.

The following Coccinelle semantic patch was used for making the change:

identifier p, probefn, removefn;

struct platform_driver p = {
  .probe = probefn,
  .remove = removefn,

As we are preparing to enable multiplatform support on EXYNOS,
we can no longer include mach/*.h or plat/*.h headers from device
drivers.

The s5p-sss driver was just enabled for EXYNOS when it used to
be used only on s5pv210, and it includes two samsung platform
specific header files for historic reasons. Fortunately, it no
longer actually needs them, so we can remove the #includes and

Currently, the driver enqueues a request only if the busy bit is
false. And every request initiates a dequeue. If 2 requests arrive
simultaneously, only one of them will be dequeued.

To avoid this senario, we will enqueue the next request irrespective
of the system condition (that is what queue is here for). Also
schedule at a tasklet immediatly after the current request is done.
The tasklet will dequeue the next request in the queue, giving
continuous loop. tasklet will exit if there are no requests in the
queue.
