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. Since it is tied to pinctrl, we place it under
'drivers/pinctrl/spear/' directory.

spi chip drivers can use the exported gpiolib interface to define their
chipselect through DT or platform data.

The driver looks ok to me, but I'll wait for Linus to take a look first
and give his ack.
