gpio: SPEAr: add spi chipselect control driver
SPEAr platform provides a provision to control chipselects of ARM PL022 Prime Cell spi controller through its system registers, which otherwise remains under PL022 control which some protocols do not want. This commit intends to provide the spi chipselect control in software over gpiolib interface. spi chip drivers can use the exported gpiolib interface to define their chipselect through DT or platform data.
