[PATCH] ARM: dts: rockchip: Fix sdmmc_pwren's pinmux setting for RK3128

[Alex Bee]

RK3128's reference design uses sdmmc_pwren pincontrol as GPIO - see [0].

Let's change it in the SoC DT as well.

This should have been part of my XPI-3128 board submission - it uses this
pin as GPIO and adapts the reference design in this regard.
Originally I had this as an override in the board DT, but later noticed
this relatively new commit in vendor's kernel. I simply forgot to add 
that commit.
