msm: dma: add 7x30 security domain abstraction
The MSM SOC's DMA controller contains several security domains. On the MSM7x00, only security domain 3 is accessible to our CPU. The 7x30, however, uses security domain 2. Fix up the register definition macros to select this appropriately, based on configured target.
