[PATCH v3 2/3] pinctrl: qcom: add driver for SM8150 SoC

Add pinctrl and GPIO driver for SM8150. Driver code is based on the
similar U-Boot drivers. All constants are taken from the corresponding
Linux driver. This drivers differs from the similar U-Boot drivers,
because SM8150 SoC have different function IDs for the same functions
on different pins.
