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.
