This is basically a rewrite of Jun's ZTE ZX pinctrl driver.  It
has quite a few significant changes from Jun's version.

 - It handles the relation between main and auxiliary controllers
   internally, and then we do not need to export core function
   pin_request().
 - Update bindings document with a ASCII figure to illustrate how this
   'hybrid' pin controller hardware works.
 - Rather than making up pin name with the fake port name and pin
   number, name the pins in the exactly same way how hardware manual
   name them.
 - Instead of encoding AON register data, calculate the offset and bit
   position from pin id.
 - Utilize the generic groups and functions support from core to save
   quite some code in our driver.
 - Simplify the data structures and add documents for important ones.
 - Clean up some unnecessary function calls.
