On R-Car V3H, RCLK can be switched between EXTALR and the On-Chip
Oscillator using mode pin MD19.

v2:
- Add Reviewed-by,
- Rename "oco" to ".oco", as it is an internal clock.
As Figure 8.1e "Block Diagram of CPG (R-Car V3H)" does not show any
divider after the On-Chip Oscillator, I assume the OCO runs at 32768 Hz.
If this turns out to be incorrect, the OCO clock rate and divider can be
updated later without any impact, as the OCO is an internal clock.
