dmaengine: remove sirfsoc driver
The CSR SiRF prima2/atlas platforms are getting removed, so this driver is no longer needed.

-* CSR SiRFSoC DMA controller
-
-See dma.txt first
-
-Required properties:
-- compatible: Should be "sirf,prima2-dmac", "sirf,atlas7-dmac" or
- "sirf,atlas7-dmac-v2"
-- reg: Should contain DMA registers location and length.
-- interrupts: Should contain one interrupt shared by all channel
-- #dma-cells: must be <1>. used to represent the number of integer
- cells in the dmas property of client device.
-- clocks: clock required
-
-Example:
-
-Controller:
-dmac0: dma-controller@b00b0000 {
- compatible = "sirf,prima2-dmac";
- reg = <0xb00b0000 0x10000>;
- interrupts = <12>;
- clocks = <&clks 24>;
- #dma-cells = <1>;
-};
-
-
-Client:
-Fill the specific dma request line in dmas. In the below example, spi0 read
-channel request line is 9 of the 2nd dma controller, while write channel uses
-4 of the 2nd dma controller; spi1 read channel request line is 12 of the 1st
-dma controller, while write channel uses 13 of the 1st dma controller:
-
-spi0: spi@b00d0000 {
- compatible = "sirf,prima2-spi";
- dmas = <&dmac1 9>,
- <&dmac1 4>;
- dma-names = "rx", "tx";
-};
-
-spi1: spi@b0170000 {
- compatible = "sirf,prima2-spi";
- dmas = <&dmac0 12>,
- <&dmac0 13>;
- dma-names = "rx", "tx";
-};
