The RTC and VBATTB don't share the MSTOP control bit (but only the bus
clock and the reset signal). As the MSTOP control is modeled though power
domains add power domain ID for the RTC device available on the
Renesas RZ/G3S SoC.

Changes in v4:
- none; this patch is new; after discussions w/ HW team internally it
  has established that the RTC and VBATTB shares different MSTOP
  settings

i.e. will queue in renesas-clk for v6.13.
