Merge tag 'amlogic-drivers-for-v6.3' of https://git.kernel.org/pub/scm/linux/kernel/git/amlogic/linux into soc/drivers

Amlogic Drivers changes for v6.3:
- Merge of immutable bindings branch with Reset & power domain binding
- Addition of NNA power domain for A311D SoC
- meson_sm.txt  conversionto dt-schema
- mark amlogic,meson-gx-pwrc bindings as deprecated
- fix of meson_sm driver by using NULL instead of 0
