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

[Macpaul Lin]

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 9b27303003f5 ("phy: mediatek: tphy: add support force phy mode switch")
Link: https://lore.kernel.org/r/20231211025624.28991-2-chunfeng.yun@mediatek.com

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.

Dear AngeloGioacchino,

Just a soft reminding about the patch has been sent a while back for the 
shared U3PHY and PCIe PHY setup for genio-1200 boards. I'm not sure if 
you've missed this patch in mail box. :)

The patch is pretty important as it lets the device tree (dts) decide 
whether to enable U3PHY or PCIe PHY. Because this is a shared hardware 
phy and could only be configured in dts to decide which function to be 
initialized, so it's something that should be included in the 
board-specific dts files.

Do you think it needs to be resubmitted, or is it still in the queue for 
review? It's meant to be ready for action from kernel version 6.8 onwards.

Looking forward to your thoughts on this. Let me know if there's 
anything else you need from my side.

As you can understand, I have to take care of many patches for each merge cycle,
and it may happen that inadvertently some patch goes out of my radar.

Please Macpaul, if this happens again, I appreciate that you remind me about
patches that I seem to leave behind, so please keep sending me such emails if
and when necessary.

Thanks!
