i.MX drivers update for 6.4:

- Use dev_err_probe() for imx-scu driver to silences EPROBE_DEFER
   messages.
 - Add LVDS LPI2C and PWM power domains for scu-pd driver.
 - A series from Jindong Yue to support module build of imx8m soc driver.
 - Update imx8m-blk-ctrl driver to scan child nodes for binding drivers.
 - Reorder structure members in imx8m-blk-ctrl driver by following
   clang-analyzer suggestion.
 - Update imx-weim bus driver to use helper function for "ranges"
   parsing.
