This patch adds the "reset-names" as reset controller for dwmmc controller.
Linaro guys had reported the issue about booting stuck.

Some SoCs are enabled the CONFIG_RESET_CONTROLLER.
then dwmmc controller are waiting for getting reset controller.
But if doesn't define "resets" property in device-tree, it should be stuck.

If use the reset-names as reset controller for dwmmc controller,
it's more stable than now.
This commit is related with the below commit.
