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

Signed-off-by: Adrian Alonso <aalonso@freescale.com>

Changes for V2: Add imx7d_lpsr_pads enums
Changes for V3: Resend
Changes for V4: Resend
Changes for V5: Remove flags SHARE_INPUT_SELECT_REG and 
 ZERO_OFFSET_VALID.
Changes for V6: Restore ZERO_OFFSET_VALID flag.
