[ Upstream commit 8182a35868db5f053111d5d9d4da8fcb3f99259d ]

Mark the VDDIO_AO18 regulator always-on and set hdmi-supply for the hdmi_tx
node to ensure HDMI is powered in the early stages of boot.

Fixes: fb72c03e0e32 ("ARM64: dts: meson-gxbb-wetek: add a wetek specific dtsi to cleanup hub and play2")
