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.

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...)

Commit 000851119e changed sha256/512 update functions to
pass more data to nx_build_sg_list(), which ends with
sg list overflows and usually with update functions failing
for data larger than max_sg_len * NX_PAGE_SIZE.
This happens because:
- both "total" and "to_process" are updated, which leads to
"to_process" getting overflowed for some data lengths
For example:
In first iteration "total" is 50, and let's assume "to_process"
is 30 due to sg limits. At the end of first iteration "total" is
set to 20. At start of 2nd iteration "to_process" overflows on:
to_process = total - to_process;
- "in_sg" is not reset to nx_ctx->in_sg after each iteration
- nx_build_sg_list() is hitting overflow because the amount of data
passed to it would require more than sgmax elements
- as consequence of previous item, data stored in overflowed sg list
may no longer be aligned to SHA*_BLOCK_SIZE
This patch changes sha256/512 update functions so that "to_process"
respects sg limits and never tries to pass more data to
nx_build_sg_list() to avoid overflows. "to_process" is calculated
as minimum of "total" and sg limits at start of every iteration.
