[PATCH v2] arm64: dts: mediatek: mt8195: Fix dtbs_check error for tphy

[Macpaul Lin]

The u3phy1 node in mt8195.dtsi was triggering a dtbs_check error.
The error message was:
  t-phy@11e30000: 'power-domains' does not match any of the regexes:
    '^(usb|pcie|sata)-phy@[0-9a-f]+$', 'pinctrl-[0-9]+'
Fix this issue by dropping 'power-domains' of u3phy1 node.

This is because MediaTek tphy dose not need to add mtcmos.  It is not
necessary to add 'power-domains'. If the power of the tphy is turned off,
it will affect other functions. From the current USB hardware design
perspective, even if mtcmos is added to the phy, it is always on.
