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 different data structure from reset_simple_data, we can not use the operation of simple reset driver. For this reason, we keep the original functions and name this version as "MTK_RST_SIMPLE". In this patch: - Add a version enumeration to separate different 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_bank_nr" to avoid confusion. This variable is used to define the quantity of reset bank. - Document mtk_reset_version and mtk_register_reset_controller.

For example, there are five infra reset banks for MT8192: 0x120, 0x130, 0x140, 0x150 and 0x730. To support this, - Change reg_ofs to rst_bank_ofs which is a pointer to base offsets of the reset register. - Add a new define RST_NR_PER_BANK to define reset number for each reset bank.
