[PATCH] arm64: dts: qcom: sdm845-lg: fix sdcard pinctrl nodes

sdcard was previously rather unreliable during boot on sdm845-lg-judyln

Identified and applied correct settings from downstream lineageos kernel.

Verified card was properly detected over 5 reboots with rootfs on sdcard.

Refer to downstream: https://github.com/LineageOS/android_kernel_lge_sdm845/blob/efa8458f79dffeb380d43b38b9403407f87d9f05/arch/arm64/boot/dts/qcom/sdm845-pinctrl.dtsi#L148-L303

Fixes: 28ae8aa3923c ("arm64: dts: qcom: add device tree for LG G7 and LG V35")
