commit d459f557ad76f449687e76fcb94f1009551dd669 upstream.

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.
