Subject: [PATCH v2 6/8] pinctrl: ingenic: Add support for the JZ4725B

Add support for the JZ4725B and compatible SoCs from Ingenic.

Signed-off-by: Paul Cercueil <paul@...pouillou.net>

Notes:
    v2: - Move dt-bindings doc update to its own patch
        - Remove ingenic,jz4725b-gpio compatible string, since it provided
          no functional difference
