[PATCH 1/6] arm64: dts: qcom: sm8250-hdk: Enable the sdhc_2 port

[ShiTou Hong <redstone.dcity@gmail.com>]

The sm8250-hdk has an on-board SD/UFS card slot,
but the SDHCI port hasn't been enabled in the dts,
so we can't use it after booting.

Enable the dts node of SDHCI for the on-board SD card slot.
Add the pinctrl node of the SD card pins.
