Enabling the GPU power domain requires that the GPU regulator is
enabled. The regulator is enabled at boot time, but gets disabled
automatically when there are no users.
This means the system might run into a failure state hanging the
whole system for the following use cases:
* if the GPU driver is being probed late (e.g. build as a
module and firmware is not in initramfs), the regulator
might already have been disabled. In that case the power
domain is enabled before the regulator.
* unbinding the GPU driver will disable the PM domain and
the regulator. When the driver is bound again, the PM
domain will be enabled before the regulator and error
appears.
Avoid this by adding an explicit regulator dependency to the
power domain.

The hdptxphy is a combo transmit-PHY for HDMI2.1 TMDS Link, FRL Link, DP
and eDP Link. Therefore, it is better to name it hdptxphy0 other than
hdptxphy_hdmi0, which will be referenced by both hdmi0 and edp0 nodes.
