Suman Anna 9afeefcf06 remoteproc: pru: Fix firmware loading crashes on K3 SoCs 
The K3 PRUs are 32-bit processors and in general have some limitations
in using the standard ARMv8 memcpy function for loading firmware segments,
so the driver already uses a custom memcpy implementation. This added
logic however is limited to only IRAMs at the moment, but the loading
into Data RAMs is not completely ok either and does generate a kernel
crash for unaligned accesses.

Fix these crashes by removing the existing IRAM logic limitation and
extending the custom memcpy usage to Data RAMs as well for all K3 SoCs.

Fixes: 1d39f4d199 ("remoteproc: pru: Add support for various PRU cores on K3 AM65x SoCs")
