i.MX drivers change for 5.9:

- Update SCU irq code to call pm_system_wakeup() in general MU IRQ
  handler, so that system can be waked up when MU IRQ arrives.
- Move i.MX SCU soc driver into imx firmware folder to get it
  initialized from i.MX SCU firmware driver.
- Clean up soc-imx-scu driver a bit by using devm_kasprintf().
- Correct postfix setting for cm40 power domain in scu-pd driver.
- Add resource management support for IMX_SCU firmware driver.
- Add more cm4 resources to i.MX SCU power domain driver.
- Select ARM_GIC_V3 from SOC_IMX8M for being able to use GICv3 driver
  in AARCH32 mode Linux on AARCH64 hardware.
