USB phys in ipq9574 use the 'L5' regulator. The commit ec4f047679d5
("arm64: dts: qcom: ipq9574: Enable USB") incorrectly specified it as
'L2'. Because of this when the phy module turns off/on its regulators,
the wrong regulator is turned off/on resulting in 2 issues, namely the
correct regulator related to the USB phy is not turned off/on and the
module powered by the incorrect regulator is affected.
Add the missing HID supplies to avoid relying on other consumers to keep
them on.
This also avoids the following warnings on boot:

Due to the fact that Lenovo Thinkpad T14s Gen6 is available with both

the panel's backlight is controlled via one of the PWMs provided by the
PMK8550 PMIC. For the OLED variant, the backlight is internal to the
panel and therefore it is not described in devicetree.
For this reason, create a generic dtsi for the T14s by renaming the

gpio and pinctrl properties from the panel node. Then add the LCD variant
dts file with the old name and describe all backlight related nodes.
