Add the "reset" as name of reset controller.
This is for preventing the wrong operation. Even if some SoC has reset
controller, doesn't define "resets" in device-tree.
Then it might be waiting for reset controller and it should be stuck.

Fixes: d6786fefe816 ("mmc: dw_mmc: add reset support to dwmmc host controller")
