WCD SPI Accces Control driver support

* wcd_spi_ac

The wcd_spi_ac driver can be added as child device node to the wcd_spi node

to indicate that the WCD SPI bus needs access control and the access needs

to be arbitrated with other masters, possibly residing on another processor.

The wcd-spi driver will parse this node and register platform_device for

this node.

Required properties:

- compatible : "qcom,wcd-spi-ac"

Example:

wcd_spi_ac {

	compatible = "qcom,wcd-spi-ac";

};
