dev, arm: Warn on PL011 DMA disable
The PL011 spec specifies a DMACR register at offset 0x48, which isn't
implemented in the model. Currently any attempt to access the register
results in a panic.
This change swaps the panic for a warning only when software writes into
DMACR to disable DMA, keeping the panic otherwise.
