arm64: dts: qcom: x1-crd: Mark the EC reset gpio as reserved
GPIO 65 from TLMM is connected to the embedded controller's active-high
reset line. Asserting it causes the fans to run at full speed during
reset and leaves the keyboard non-functional afterwards.
Reserve it to prevent Linux from requesting or reconfiguring it.
