Zhou Yanjie April 10, 2021, 6:54 p.m.
Add support for probing the pinctrl-ingenic driver on the
JZ4730 SoC from Ingenic.

This driver is derived from Paul Boddie. It is worth to
noting that the JZ4730 SoC is special in having two control
registers (upper/lower), so add code to handle the JZ4730
specific register offsets and some register pairs which have
2 bits for each GPIO pin.

Tested-by: H. Nikolaus Schaller <hns@goldelico.com>  # on Letux400

Notes:
    v3:
    New patch.
    
    v3->v4:
    1.Use "lcd-special" and "lcd-generic" instead "lcd-16bit-tft".
    2.Adjust function names to avoid confusion.
    3.Improve the structure of some functions.
    4.Modify the format of comment.
    5.Simplify code using GENMASK.
    6.Drop unnecessary mask.
