pinctrl: add a Cirrus ep93xx SoC pin controller

Browse Source 
Add a pin control (only multiplexing) driver for ep93xx SoC so
we can fully convert ep93xx to device tree.

This driver is capable of muxing ep9301/ep9302/ep9307/ep9312/ep9315
variants, this is chosen based on "compatible" in device tree.
