Since the Lenovo Thinkpad T14s Gen6 is available with an OLED, add
dedicated a dedicated dts for it.

This is needed because the backlight is handled differently for OLED
panels when compared to LCD ones.

Probably you need different compatibles, e.g.
"lenovo,thinkpad-t14s-oled", "lenovo,thinkpad-t14s", "qcom,x1e78100"...

It's likely that original DTS should also get a new front compatible
"-lcd" or whatever you find useful.
