dmaengine: add Qualcomm Technologies HIDMA channel driver
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.
