armv8: K3: j721e: Add DSP internal memory regions in MMU table
The A72 U-Boot code supports early load and boot of a number of
remote processors including the C66_0 and C66_1 DSPs. The current
code supports only loading into the DDR regions which were already
given the appropriate memory attributes. The C66 DSPs also have L1
and L2 internal memory regions that can behave as normal-memories.
Add a new entry to the J721E MMU table covering these regions with
the appropriate memory attributes to allow the A72 U-Boot code to
support loading directly into these memory regions.

remoteproc: k3-dsp: Add a sanity check for DSP boot address alignment
The DSP remote processors on K3 SoCs require a boot register to be
programmed with a boot address, and these boot addresses need to be
aligned on certain address boundaries. The current code does not have
any error checks, and relies on the System Firmware to perform the
checking. Add logic to perform this sanity check within the remoteproc
driver itself to detect these anomalies specifically, and print a
meaningful trace. This avoids the cumbersome debug of root-causing
such failures from the corresponding TI-SCI failure.
The C66x and C71x DSP cores have different alignment needs and are
as follows:
C66x DSP = 1 KB (0x400)
C71x DSP = 2 MB (0x200000)

dma_unmap_single(), which performs cache invalidation internally,
