[PATCH v2 04/16] arm64: dts: qcom: x1e80100-dell-xps13-9345: Mark the EC reset gpio as reserved

[Abel Vesa]

GPIO 65 from TLMM is used by the embedded controller as its reset line.

On some devices, toggling the embedded controller reset line makes the
device not power up at all, unless the battery is unplugged.

So reserve it in order to prevent Linux from requesting or
reconfiguring it.
