[PATCH] riscv: dts: starfive: Set EMMC vqmmc maximum voltage to 3.3V on JH7110 boards

[Shengyu Qu]

Currently, for JH7110 boards with EMMC slot, vqmmc voltage for EMMC is
fixed to 1.8V, while the spec needs it to be 3.3V on low speed mode and
should support switching to 1.8V when using higher speed mode. Since
there are no other peripherals using the same voltage source of EMMC's
vqmmc(ALDO4) on every board currently supported by mainline kernel,
regulator-max-microvolt of ALDO4 should be set to 3.3V.
