The old hardware is one bit per reset control, and does not have separate registers for bit set, clear and read-back operations. This matches the scheme supported by the simple reset driver. However, because we need to use our data structure "struct mtk_reset", we can not use the operation of simple reset driver. We keep the original functions and name this version as "MTK_RST_SIMPLE". In this patch: - Add a version enum to separate different MediaTek reset hardware. - Merge the reset register function of simple and set_clr into one function "mtk_register_reset_controller". - Rename input variable "num_regs" to "rst_set_nr" to avoid confusion. This variable is used to define the number of reset set. - Rename "regofs" to "reg_ofs". - Adjust delaration type for mtk_register_reset_controller().

We use it to store reset register data and store reset controller device. It's more easy to manager the data for each reset controller. - Extract container_of in update functions to to_mtk_clk_rst_data().
