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.

This allows basic support for SD highspeed cards but no UHS-I mode
got ready due to the propagated defer-probe error from RK805.

keep-power-in-suspend was invented for SDIO only, so it should
not be used for eMMC node.

The power-tree on the rk3399-firefly did not completely match the
documentation and vendor devicetree. It was also missing some
supply-hirarchy information and some regulator-gpio names did not
match the schematics. Fix this for the existing regulators before
introducing new things.

Firefly-rk3399 is a bord from T-Firefly, you can find detail about
it here:
http://en.t-firefly.com/en/firenow/Firefly_RK3399/

This patch add basic node for the board and make it able to bring
up.

Peripheral works:
- usb hub which connect to ehci controller;
- UART2 debug
- eMMC
- PCIe

Not work:
- USB 3.0 HOST, type-C port
- sdio, sd-card

Not test for other peripheral:
- HDMI
- Ethernet
- OPTICAL
- WiFi/BT
- MIPI CSI/DSI
- IR
- EDP/DP
