arm64: dts: qcom: qrb2210-rb1: disable cluster power domains

If cluster domain idle state is enabled on the RB1, the board becomes
significantly less responsive. Under certain circumstances (if some of
the devices are disabled in kernel config) the board can even lock up.

It seems this is caused by the MPM not updating wakeup timer during CPU
idle (in the same way the RPMh updates it when cluster idle state is
entered).

Disable cluster domain idle for the RB1 board until MPM driver is fixed
to cooperate with the CPU idle states.
