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
- Add iomuxc-lpsr gpio group id's
- Use flag ZERO_OFFSET_VALID and SHARE_INPUT_SELECT_REG to
properly set pads from iomuxc-lpsr domain
