ffda1089dd arm: mach-k3: Move R5 specific code into new r5/ directory
This makes it clear these are only to be used by the R5 builds of SPL.
And this will be used to later more cleanly split the two builds.

e4439cadb6 arm: mach-k3: am62ax: Move board selection to mach-k3
Currently each set of board targets from a vendor is selected inside
the board directory for that vendor. This has the problem of multiple
targets, one from each vendor, being selectable at the same time.
For instance you can select both TARGET_AM654_A53_EVM and
TARGET_IOT2050_A53 in the same build.

To fix this we need to move the target board choice to a common location
for each parent SoC selection. Do this in arch/arm/mach-k3.

d50f82815d arm: mach-k3: *: dev-data: Update to use ARRAY_SIZE
Instead of hard-coding the count of entries manually, use ARRAY_SIZE
to keep the count updates appropriately.

28e5e95bf8 arm: mach-k3: am62a7: Enable QoS for DSS
Enable Quality of Service (QoS) blocks for Display SubSystem (DSS), by
servicing the DSS - DDR traffic from the Real-Time (RT) queue. This is
done by setting the DSS DMA orderID to 8.

The C7x and VPAC have been overwhelming the DSS's access to the DDR
(when it was accessing via the Non Real-Time (NRT) Queue), primarily
because their functional frequencies, and hence DDR accesses, were
significantly higher than that of DSS. This led the display to flicker
when certain edgeAI models were being run.

With the DSS traffic serviced from the RT queue, the flickering issue
has been found to be mitigated.

The am62a qos files are auto generated from the k3 resource partitioning
tool.

Section-3.1.12, "QoS Programming Guide", in the AM62A TRM[1], provides
more information about the QoS, and section-14.1, "System Interconnect
Registers", provides the register descriptions.
