Subject: [PATCH] arm64: dts: qcom: sm7125-xiaomi-common: Add reset-gpios for ufs_mem_hc

The SC7180/SM7125 SoCs have a special pin for UFS reset. Generally, this
pin is the same for all devices on the same SoC because it is hardcoded
in the pinctrl driver. Therefore, it might seem appropriate to add this
pin configuration in sc7180.dtsi. However, this pin is defined in the
device-specific DTS files instead of the SoC-level DTS files in all
Qualcomm DTS. To maintain consistency with this approach, we will follow
the same style.

Add reset-gpios to ufs_mem_hc.
