Subject: [PATCH v1 2/2] arm64: dts: qcom: sc7180: trogdor: SD-card GPIO pin set bias-pull up

Trogdor board does not have external pull-up for cd-gpio. Set this pin
to internal pull-up for sleep config to avoid frequent regulator toggle
events.

This change is aligned with Qualcomm's DT change posted at:
