Avoid adding the final operation within the loop, but instead add it

When we process the last request of data, and the request contains user
data, the loop in mv_cesa_ahash_dma_req_init() marks the first data size
as being iter.base.op_len which does not include the size of the cache
data. This means we end up hashing an insufficient amount of data.
Fix this by always including the cache size in the first operation
length of any request.
This has the effect that for a request containing no user data,
iter.base.op_len === iter.src.op_offset === creq->cache_ptr
As a result, we include one further change to use iter.base.op_len in
the cache-but-no-user-data case to make the next change clearer.

Use the presence of the scatterlist to determine whether we should load
any new user data to the engine. The following shall always be true at
this point:
iter.base.op_len == 0 === iter.src.sg
In doing so, we can:
1. eliminate the test for iter.base.op_len inside the loop, which
makes the loop operation more obvious and understandable.
2. move the operation generation for the cache-only case.
This prepares the code for the next step in its transformation, and also
uncovers a bug that will be fixed in the next patch.

Add a helper to add the fragment operation block followed by the DMA

Although at the moment this pattern only strictly appears at one site,
two other sites can be factored as well by slightly changing the order
in which the DMA operations are performed. This should be harmless as
the only thing which matters is to have all the data loaded into SRAM

In fact there is currently no need for those operations to be

It'll give us a slightly more accurate clock in some cases.
Not sure why I went for the down+up approach originally. Perhaps
I was thinking we can go back and forth betwen the two frequencies

they can't represent certain CEA/HDMI modes accurately. If we see a mode
coming in via detailed timings which otherwise matches one of the
CEA/HDMI modes except the clock is just a bit off, let's assume that the
intention was for that mode to be one of the CEA/HDMI modes and go ahead
and fix up the clock to match the CEA/HDMI spec exactly (well, as close
as we can get with the 1 kHz resolution we use).
This should help code that's looking for an exact clock match (eg. i915

Some code may perform racy by design memory reads. This could be

To hide such accesses from KASAN this patch introduces
READ_ONCE_NOCHECK() macro. KASAN will not check the memory
accessed by READ_ONCE_NOCHECK(). The KernelThreadSanitizer
(KTSAN) is going to ignore it as well.
This patch creates __read_once_size_nocheck() a clone of
__read_once_size(). The only difference between them is
'no_sanitized_address' attribute appended to '*_nocheck'
function. This attribute tells the compiler that instrumentation
of memory accesses should not be applied to that function. We
declare it as static '__maybe_unsed' because GCC is not capable
to inline such function:
