soc: mediatek: Support reset bit mapping in mmsys driver
- Reset ID must starts from 0 and be consecutive, but
  the reset bits in our hardware design is not continuous,
  some bits are left unused, we need a map to solve the problem
- Use old style 1-to-1 mapping if .rst_tb is not defined

/**
* struct mtk_mmsys_driver_data - Settings of the mmsys
* @clk_driver: Clock driver name that the mmsys is using
* (defined in drivers/clk/mediatek/clk-*.c).
* @routes: Routing table of the mmsys.
* It provides mux settings from one module to another.
* @num_routes: Array size of the routes.
* @sw0_rst_offset: Register offset for the reset control.
* @num_resets: Number of reset bits that are defined
* @is_vppsys: Whether the mmsys is VPPSYS (Video Processing Pipe)
* or VDOSYS (Video). Only VDOSYS needs to be added to drm driver.
* @vsync_len: VSYNC length of the MIXER.
* VSYNC is usually triggered by the connector, so its length is a
* fixed value when the frame rate is decided, but ETHDR and
* MIXER generate their own VSYNC due to hardware design, therefore
* MIXER has to sync with ETHDR by adjusting VSYNC length.
* On MT8195, there is no such setting so we use the gap between
* falling edge and rising edge of SOF (Start of Frame) signal to
* do the job, but since MT8188, VSYNC_LEN setting is introduced to
* solve the problem and is given 0x40 (ticks) as the default value.
* Please notice that this value has to be set to 1 (minimum) if
* ETHDR is bypassed, otherwise MIXER could wait too long and causing
* underflow.
*
* Each MMSYS (multi-media system) may have different settings, they may use
* different clock sources, mux settings, reset control ...etc., and these
* differences are all stored here.
