Subject: [PATCH v1 07/43] pinctrl: add a Cirrus ep93xx SoC pin controller
This adds 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.
