pinctrl: sunxi: support multiple pin controller
Add support for multiple pin controller instances.
First remove the static definition of the sunxi gpio chip struct and fill
the dynamically struct instead.
Then define a new pin_base field in the sunxi_pinctrl_desc which will be
used to specify the gpiochip base pin.
