[PATCH 0/2] Add 48-bit DMA mask for TI K3 remoteproc devices

[Beleswar Padhi]

The TI K3 R5F and C6x cores can address 48-bit memory space through the
Region Address Translator (RAT) unit. Whereas the TI K3 C7x has a native
48-bit address bus. RAT is usually programmed from the firmware itself.
Configure the remoteproc device DMA mask to 48 bits to enable full
addressing capability for DMA operations.

Testing done:
1. Verified above devices are able to access 48-bit addresses with
   compatible firmware.
2. Verified IPC with Cortex-R5F and C7x DSPs on TI J784S4 EVM.
3. Verified none of the patch generate any new warning/errors.

Thanks,
Beleswar
