ECR #399840 - OpenCL Runtime HW Debug support development - resolve the TDR issues on Kaveri.

	1. update the resource descriptors in the runtime trap handler to match those in the HSA HW debug implementation
	2. force to use SDMA for device memory map function, which is called when using clHwDbgSetGlobalMemoryAMD() and clEnqueueMapImage() functions, for HW debug
