[PATCH v2 4/5] dmaengine: dma: Rename driver and config

[Kedareswara rao Appana <appana.durga.rao@xilinx.com>]

In the existing vdma driver support for
AXI DMA and CDMA got added so the driver is no
longer VDMA specific.

This patch renames the driver and DT binding doc to xilinx_dma
and updates the Kconfig description for all the DMAS.
