coe: keep track of registered buffers
...
Modify logic of CoE IOCTLs REGISTER_BUFFER and CAPTURE_REQUEST to use
pre-registered buffers identified with an index. Instead of userspace
specifying a DMA_BUF ID for each capture request it will now specify a
simple index 0-3 of a pre-registered DMA_BUF.

coe: move Rx descriptor mem from uncached region
...
RCE no longer manipulates Rx descriptor ring with CPU accesses, but uses
a DMA engine instead. Rx descriptor mem can be moved out of uncached
RCE region.
As RCE uncached region is now empty - remove it.

coe: move PKTINFO from uncached RCE region
...
RCE firmware no longer writes anything to PKTINFO buffers and just reads
them. PKTINFO can be moved out of uncached RCE memory region and treated
like a normal allocation.

coe: make CoE capture more robust
...
Modify CoE capture logic a bit to make it more robust and error-proof:
- RCE Rx queue limit size is 16, no point to have 32 elements long queue
in kernel.
- Pass kernel's queue length to RCE when opening a channel so it can be
validated (to not exceed RCE max depth)
- validate image buffers IOVA addresses and buffer length before queuing
to RCE
