Subject: arm64: dts: rockchip: correct vqmmc voltage for rk3399 platforms

From: Shawn Lin <shawn.lin@rock-chips.com>

commit b31ce3041787b61f2dad39d2dcda5c4a81d10e2b upstream.

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.
