Argh: I submitted the pre-dtbs_check version. Thanks for checking.

I recommend splitting this part into a separate patch, and
adding an appropriate "Fixes" tag to it.

I'm with you on that. Adding the resets to the existing controllers
should be a separate patch.

RK3328 SoC has a fourth mmc controller called SDMMC_EXT. Some
boards have sdio wifi connected to it. In order to use it
one would have to add the pinctrls from sdmmc0ext group which
is done on board level.
Signed-off-by: Alex Bee <knaerzche@gmail.com>

Changes in v2:
- fixed node name in accordance to DT bindings (Johan)
- seperated patch which adds reset controls for the
other mmc controllers (Chen-Yu)

The DW MCI controller driver will use them to reset the IP block before
initialisation.
