Subject: [PATCH] arm64: dts: rockchip: correct vqmmc voltage for rk3399
platforms

The vcc_sd or vcc_sdio used for IO voltage for sdmmc and sdio interface on rk3399 platform have a limitation that it can't be larger than 3.0v, otherwise it has a potential risk for the chip. Correct all of them.

Fixes 171582e00db1 ("arm64: dts: rockchip: add support for firefly-rk3399 board")

Fixes 2c66fc34e945 ("arm64: dts: rockchip: add RK3399-Q7 (Puma) SoM")

Fixes 8164a84cca12 ("arm64: dts: rockchip: Add support for rk3399 sapphire SOM")
