i.MX fixes for 5.8:

- Fix LDO1 and LDO2 voltage range for a couple of i.MX8M board device
  trees.
- Fix i.MX8MP UID fuse offset in i.MX8M SoC driver.
- Fix watchdog configuration in imx6ul-kontron device tree.
- Fix one build warning seen on building soc-imx8m driver with
  x86_64-randconfig.
- Add missing put_device() call for a couple of mach-imx PM functions.
