arm64: dts: mediatek: mt8395-genio-1200-evk: add u3port1 for xhci1

Browse Source 
This patch fixes an issue where xhci1 was not functioning properly because
the state and PHY settings were incorrect.

The introduction of the 'force-mode' property in the phy-mtk-tphy driver
allows for the correct initialization of xhci1 by updating the Device Tree
settings accordingly.

The necessary fixup which added support for the 'force-mode' switch in the
phy-mtk-tphy driver.
commit 9b27303003 ("phy: mediatek: tphy: add support force phy mode switch")

Prior to this fix, the system would exhibit the following probe failure messages
for xhci1:
  xhci-mtk 11290000.usb: supply vbus not found, using dummy regulator
  xhci-mtk 11290000.usb: uwk - reg:0x400, version:104
  xhci-mtk 11290000.usb: xHCI Host Controller
  xhci-mtk 11290000.usb: new USB bus registered, assigned bus number 5
  xhci-mtk 11290000.usb: clocks are not stable (0x1003d0f)
  xhci-mtk 11290000.usb: can't setup: -110
  xhci-mtk 11290000.usb: USB bus 5 deregistered
  xhci-mtk: probe of 11290000.usb failed with error -110

With the application of this dts fixup, the aforementioned initialization errors
are resolved and xhci1 is working.
