coresight: tmc: Configure DMA mask appropriately
[ Upstream commit a3959c50b02f57df4c4e4f14f632220f1c0b1f79 ]
Before making any DMA API calls, the ETR driver should really be setting
its masks to ensure that DMA is possible. Especially since it can
address more than the 32-bit default mask set by the AMBA bus code.
