To declare the reset data easier, we add a strucure to do this instead
of using many input variables to mtk_register_reset_controller().
- Add mtk_clk_rst_desc to define the reset description when registering
the reset controller.
- Rename "mtk_reset" to "mtk_clk_rst_data". We use it to store data of
reset controller.
- Document mtk_clk_rst_desc and mtk_clk_rst_data.
- Modify the documentation of mtk_register_reset_controller.
- Extract container_of in update functions to to_mtk_clk_rst_data().
