Add device nodes for the Timer Units (TMU) on the R-Mobile APE6 SoC,
and the clocks serving them.
Note that TMU channels 1 and 2 are not added, as their interrupts are
not wired to the interrupt controller for the AP-System Core (INTC-SYS),
only to the interrupt controller for the AP-Realtime Core (INTC-RT).
