sunxi: add pinctrl (UCLASS_PINCTRL) support for sunxi
This change adds a full device-model pinctrl driver for sunxi (tested with
sun50iw1p1) based on the support available in Linux.
Details are:
* implements a driver for pinctrl devices and assigns sun50i-a64-pinctrl
and sun50i-a64-r-pinctrl to it
* dynamically creates the driver_data for a sunxi_gpio (see sunxi_gpio.c)
driver and binds it to the same device-tree node
* lifts and reuses the pinctrl-sunxi.h and pinctrl-sun50i-a64.c files from
Linux (thanks to Maxime and Andre) and adds a pinctrl-sun50i-a64-r.c (to
be picked up for inclusion into Linux again)
