This patch adds support for hidma engine. The driver
consists of two logical blocks. The DMA engine interface
and the low-level interface. The hardware only supports
memcpy/memset and this driver only support memcpy
interface. HW and driver doesn't support slave interface.

+Qualcomm Technologies HIDMA Channel driver

+Required properties:
+- compatible: must contain "qcom,hidma"
This should be "qcom,hidma-1.0" to match the example and driver. I
