Subject: [PATCH v4 0/4] meson-ee-pwrc: support for Meson8/8b/8m2 and GX

This series adds support for all "older" SoCs to the meson-ee-pwrc
driver. I wanted to compare as much as I could between my Meson8b EC-100
(Endless Mini) and the Le Potato board so I added support for GXBB, GXL
and GXM as well as for the SoCs that I'm actually working on. I will
send the ARM64 dts patches once all of this is reviewed and merged.

I successfully tested the Meson8b part on EC-100 where u-boot does not
initialize the VPU controller. So this the board where I have been
struggling most.

Kevin, I'm not sure if this can still make it into v5.8. If the
series as a whole can't make it for some reason then I'd appreciate if
patches #1 and #2 could end in v5.8 so I can push the .dts patches for
v5.9.


Changes since v3 at [2]:
- added Rob's Reviewed-by to patches #1 and #2 - thank you!
- add a GX_ prefix to AO_RTI_GEN_PWR_{SLEEP0,ISO} and add new #defines
  for MESON8_AO_RTI_GEN_PWR_{SLEEP0,ISO} based on Neil's suggestion.
- rename meson8_pwrc_mem_eth to meson_pwrc_mem_eth as suggested by
  Neil (thanks!) because it's the same for all platforms
- rename gxbb_pwrc_vpu to gx_pwrc_vpu as suggested by Neil (thanks)
- added Neil's Reviewed-by to patches #3 and #4 

Changes since v2 at [1]:
- don't remove the "reset-names" property from the main description
  (only make it optional and switch from items to minItems) to fix
  a dt_binding_check found by Rob (or his bot) - thanks and sorry!

Changes since v1 at [0]:
- rename PWRC_GXBB_ETH_ID to PWRC_GXBB_ETHERNET_MEM_ID. Spotted by
  Neil, thanks!
- update cover-letter since Neil confirmed (thanks!) that the "dvin"
  reset really belongs to the VPU on GXBB, GXL and GXM
- removed RFC status
