Most significant part of JQCR (Job Queue Control Register) contains
bits that control endianness: ILE - Immediate Little Endian,
DWS - Double Word Swap.
The bits are automatically set by the Job Queue Controller HW.

Unfortunately these bits are cleared in SW when submitting descriptors
via the register-based service interface.
>From LS1021A:
JQCR_MS = 08080100 - before writing: ILE | DWS | SRC (JR0)
JQCR_MS = 30000100 - after writing: WHL | FOUR | SRC (JR0)

This would cause problems on little endian caam for descriptors
containing immediata data or double-word pointers.
Currently there is no problem since the only descriptors ran through
this interface are the ones that (un)instantiate RNG.

Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

This patch introduces the crypto skcipher interface which aims
to replace both blkcipher and ablkcipher.

It's very similar to the existing ablkcipher interface.  The
main difference is the removal of the givcrypt interface.  In
order to make the transition easier for blkcipher users, there
is a helper SKCIPHER_REQUEST_ON_STACK which can be used to place
a request on the stack for synchronous transforms.

LS1021A is a QorIQ SoC having little endian CAAM.

There are a few differences b/w QorIQ and i.MX from CAAM perspective:

1. i.MX platforms are somewhat special wrt. 64-bit registers:
-big endian format at 64-bit level: MSW at address+0 and LSW at address+4
-little endian format at 32-bit level (within MSW and LSW)
and thus need special handling.

2. No CCM (clock controller module) for QorIQ.
No CAAM clocks to enable / disable.

A new Kconfig option - CRYPTO_DEV_FSL_CAAM_LE - is added to indicate
CAAM is little endian (*). It is hidden from the user (to avoid
misconfiguration); when adding support for a new platform with LE CAAM,
either the Kconfig needs to be updated or the corresponding defconfig
needs to indicate that CAAM is LE.
(*) Using a DT property to provide CAAM endianness would not allow
for the ifdeffery.

In order to keep changes to a minimum, the following changes
are postponed:
-endianness fix of the last word in the S/G (rsvd2, bpid, offset),
fields are always 0 anyway;
-S/G format fix for i.MX7 (yes, i.MX7 support was not added yet,
but still...)

GHASH table algorithm is using a big endian key.
In little endian machines key will be LE ordered.
After a lxvd2x instruction key is loaded as it is,
LE/BE order, in first case it'll generate a wrong
table resulting in wrong hashes from the algorithm.

Bug affects only LE machines.
In order to fix it we do a swap for loaded key.
