[U-Boot] [PATCH 4/6] rockchip: pinctrl: rk3328: use gpio instead of sdmmc-pwren

[Kever Yang]

SDMMC-PWREN is a pin to control voltage for SDMMC IO, it may
be high active or low active, the dwmmc driver always assume
the sdmmc-pwren as high active.

Kernel treat this pin as fixed regulator instead of a pin from
controller, and then it can set in dts file upon board schematic,
that's a good solution, we can also do this in u-boot.
