Match the change for the XPS 13 (a41d2314) as the board is identical
between the XPS and the Latitude/Inspiron.
This allows us not to rely on the boot firmware to set up the pinctrl
for the eDP HPD line of the internal display.
Fixes: e7733b42111c ("arm64: dts: qcom: Add support for Dell Inspiron 7441 / Latitude 7455")

Same comment on the commit identification.
Also, are the boards identical ? I don't think that statement is true,
say the "board DP here is identical" but there are GPIOs on the PCBs
which read back different values to differentiate.
They are not identical PCBs.

Once fixed.
