ASoC: remove sirf prima/atlas drivers

Browse source 
The CSR SiRF prima2/atlas platforms are getting removed, so this driver
is no longer needed.

SiRF internal audio CODEC
Required properties:
- compatible : "sirf,atlas6-audio-codec" or "sirf,prima2-audio-codec"
- reg : the register address of the device.
- clocks: the clock of SiRF internal audio codec
Example:
audiocodec: audiocodec@b0040000 {
compatible = "sirf,atlas6-audio-codec";
reg = <0xb0040000 0x10000>;
clocks = <&clks 27>;

* SiRF SoC USP module
Required properties:
- compatible: "sirf,prima2-usp-pcm"
- reg: Base address and size entries:
- dmas: List of DMA controller phandle and DMA request line ordered pairs.
- dma-names: Identifier string for each DMA request line in the dmas property.
These strings correspond 1:1 with the ordered pairs in dmas.
One of the DMA channels will be responsible for transmission (should be
named "tx") and one for reception (should be named "rx").
- clocks: USP controller clock source
- pinctrl-names: Must contain a "default" entry.
- pinctrl-NNN: One property must exist for each entry in pinctrl-names.
Example:
usp0: usp@b0080000 {
compatible = "sirf,prima2-usp-pcm";
reg = <0xb0080000 0x10000>;
clocks = <&clks 28>;
dmas = <&dmac1 1>, <&dmac1 2>;
dma-names = "rx", "tx";
pinctrl-names = "default";
pinctrl-0 = <&usp0_only_utfs_pins_a>;
};
