Ulf Hansson 34d4379b6f arm64: dts: qcom: sm8250: Disable the not yet supported cluster idle state
[ Upstream commit cadaa773bc ]

To support the deeper cluster idle state for sm8250 platforms, some
additional synchronization is needed between the rpmh-rsc device and the
CPU cluster PM domain. Until that is supported, let's disable the cluster
idle state.

This fixes a problem that has been reported for the Qcom RB5 platform (see
below), but most likely other sm8250 platforms suffers from similar issues,
so let's make the fix generic for sm8250.
