arm64: dts: rockchip: Fix vcc_sdio regulator max voltage on Pinebook Pro
The vcc_sdio regulator supports 1.8V to 3.4V output range according to
its datasheet.
The current DT incorrectly limits the max voltage to 3.0V. This limit
causes issues issues downstream with u-boot, which refuses to apply the
out-of range value, and falls back to the minimum in that range: 1.8V.
This is insufficient to power the SD card, so driver initialisation
fails and booting from it does not work.
Set regulator-max-microvolt to 3400000 µV to match hardware capability.
This matches the rk3399-orangepi for the same regulator.
