* Extend pinctrl-imx driver to support iomux lpsr conntroller,
* iMX7D has two iomuxc controllers, iomuxc controller similar as
  previous iMX SoC generation and iomuxc-lpsr which provides
  low power state rentetion capabilities on gpios that are part of
  iomuxc-lpsr (GPIO1_IO7..GPIO1_IO0).
* Use IOMUXC_LPSR_SUPPORT and iput_val most significant bits to
  properly configure iomuxc/iomuxc-lpsr settings.

* Change from v1 to v2:
  - Add suggested comment for input select register shared between
    iomuxc-lpsr and normal iomuxc controller.
  - Use IOMUXC_LPSR_MASK to extract pad group id and aling pin_id to
    16 bit representation.
* Change from v2 to v3
  - Use devm_ioremap_resource instead of of_iomap to get iomuxc-lpsr
    base register address.

I'm waiting for Shawn to review these patches.
