I've rebased this series on the next-20170413 for sanity sake, and
realized there doesn't appear to be a way to select CONFIG_IMX_GPCV2.
I forced it using 'default y' and configured with imx_v6_v7_defconfig.
Now my board is booting. Before this series is applied, it may be good
to have CONFIG_IMX_GPCV2 selected specifically for iMX7 platform,
otherwise there will be boot regressions.
I'd encounter a backtrace with next-20170413 + imx_v6_v7_defconfig +
CONFIG_IMX_GPCV2=y
