Some of the SRQ types are created using a WQ, and the WQ requires a
different parameter set to mlx5_umem_find_best_quantized_pgoff() as it has
a 5 bit page_offset.
Add the umem to the mlx5_srq_attr and defer computing the PAS data until
the code has figured out what kind of mailbox to use. Compute the PAS
directly from the umem for each of the four unique mailbox types.
This also avoids allocating memory to store the user PAS, instead it is
written directly to the mailbox as in most other cases.

Since devx uses the new rdma_for_each_block() to fill the PAS it can also
use ib_umem_find_best_pgsz().
However, the umem constructionin devx is complicated, the umem must still
respect all the HW limits such as page_offset_quantized and the IOVA
alignment.
Since we don't know what the user intends to use the umem for we have to
limit it to PAGE_SIZE.
There are users trying to mix umem's with mkeys so this makes them work
reliably, at least for an identity IOVA, by ensuring the IOVA matches the
selected page size.
Last user of mlx5_ib_get_buf_offset() so it can also be removed.

This fixes a bug where the page_offset was not being considered when
building a CQ. The HW specification says it 'must be zero', so use
a variant of mlx5_umem_find_best_quantized_pgoff() with a 0 pgoff_bitmask
to force this result.

The RQ WQ created when making a raw ethernet QP copies the PAS list from
a dummy QPC command created earlier in the flow. The WQC and QPC PAS lists
are not fully compatible as the page_offset is a different size.
Create the RQ WQ's PAS list directly and do not try to copy it from
another command structure.
Like the prior patch, this also means that badly aligned buffers were not
correctly rejected.

This fixes a subtle bug, the WQ mailbox has only 5 bits to describe the
page_offset, while mlx5_ib_get_buf_offset() is hard wired to only work
with 6 bit page_offsets.
Thus it did not properly reject badly aligned buffers.

SRQ uses a quantized and scaled page_offset, which is another variation of
ib_umem_find_best_pgsz(). Add mlx5_umem_find_best_quantized_pgoff() to
perform this calculation for each mailbox. A macro shows how the
calculation is directly connected to the mailbox format.
This new routine replaces the limited mlx5_ib_cont_pages() and
mlx5_ib_get_buf_offset() pairing which would reject valid configurations
rather than adjust the page_size to make it work.
In turn this is much more aggressive about choosing large page sizes for
these objects and when THP is enabled it will now often find a single page
solution.

The conversion to the generic kmap_atomic() implementation missed the fact
that xtensa's fixmap works bottom up while all other implementations work
top down. There is no real reason why xtensa needs to work that way.
Cure it by:
- Using the generic fix_to_virt()/virt_to_fix() functions which work top
down
- Adjusting the mapping defines
- Using the generic index calculation for the non cache aliasing case
- Making the cache colour offset reverse so the effective index is correct
While at it, remove the outdated and misleading comment above the fixmap
enum which originates from the initial copy&pasta of this code from i386.

Playing with very low period sizes may lead to timeouts when awaiting

appearing in the middle of trigger(stop).
Stream is unprepared during trigger(stop) where PAUSE_STREAM IPC gets
invoked. However, all data that is already mixed in DSP firmware's mixer
stream will still be played regardless of the pause. For offload streams,
this means possibility for another NOTIFY_POSITION to process. Keep these
