pinctrl: Add driver support for Amlogic SoCs

Browse Source 
Add a new pinctrl driver for Amlogic SoCs. All future Amlogic
SoCs pinctrl drives use this, such A4, A5, S6, S7 etc. To support
new Amlogic SoCs, only need to add the corresponding dts file.

This is the driver for the pin controller found on Amlogic SoCs.
This driver is simplify subsequent support for new amlogic SoCs,
to support new Amlogic SoCs, only need to add the corresponding dts file,
no additional binding header files or C file are added.
