arm64: dts: qcom: qcs615-ride: fix sdhc_2 vqmmc-supply for UHS-I mode
SD card is detected as SDHS instead of UHS-I because sdhc_2 was
configured with vreg_s4a as vqmmc-supply, which cannot switch
between 1.8V and 3.3V.
Switch vqmmc-supply to vreg_l2a and update its voltage range to
1800000-2960000 uV to enable proper UHS-I signaling.
