Subject: [PATCH v2 0/4] ARM64: dts: meson-gx: fix VPU init for non-vendor u-boot

On the Amlogic Gx SoCs (GXBB, GXL & GXM), the VPU power domain is initialized
by the vendor U-Boot code, but running mainline U-boot has been possible
on these SoCs. But lacking such init made the system lock at kernel boot.

A PM Power Domain driver has been pushed at [1] to solve the main issue.

This patchset depends on the the following patchsets :
- [1] soc: amlogic: add support for Meson GX VPU Domains
- [2] reset: meson: add level reset support for GX SoC family
- [3] clk: meson: gxbb: Add VPU and VAPB clocks

Changes since v1 at [4] :
 - Dropped hdmi-supply in hdmi node until 4.16
 - set 5v regulator always-on for now
