Subject: [PATCH v6 10/16] clk: mediatek: reset: Add new register reset function with device
Using device to register reset controller is a better implementation in
current drivers. Howerver, some clock drviers of MediaTek only provide
device_node.
Therefore, we still remain the register reset function with device_node
and add a new function with device to register reset controller.
