Ulaş Sertan Kemeç a2edd99159 arch/arm/am67: Add rptun IPC with the Linux A53 (remoteproc/rpmsg).
Connects the R5F to Linux remoteproc over the NAVSS mailbox.

The mailbox ISR only drains the FIFO and acknowledges; OpenAMP delivery is
deferred to HPWORK, because the rpmsg rx path takes mutexes and allocates.

The resource table publishes two vdevs, rpmsg and virtio-net, leaving every
vring address FW_RSC_ADDR_ANY: Linux allocates them from the R5F DMA pool and
rejects fixed addresses outside it.

Shared IPC memory is mapped Non-cacheable, since the R5F is not coherent with
the A53 and cached mappings leave NuttX reading stale vring state.

Also drops the duplicate arm_mpu.c from CHIP_CSRCS.
