[PATCH] arm64: dts: qcom: glymur-crd: Add pull-up for SD card detect

[Monish Chunara]

The SD card detect signal is active low and requires a defined high
level when no card is inserted. With the GPIO bias disabled, the
card-detect input can be left floating and result in spurious
interrupts.

Enable the internal pull-up on the SD card detect GPIO to keep the
signal at a defined level when the card is absent and avoid spurious
card-detect interrupts.

Deserves a Fixes tag, doesn't it?
