clk: renesas: r9a09g011: Add TIM clock and reset entries
Add Compare-Match Timer (TIM) clock and reset entries to CPG driver. The TIM IP on the RZ/V2M comes with 32 channels, but the ISP has full control of channels 0 to 7, and channels 24 to 31. Therefore Linux is only allowed to use channels 8 to 23. The TIM has shared peripheral clock with other modules, so mark it as critical clock.
