[ Upstream commit cadaa773bcf161184fa428180516bae33a7bc667 ]
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.
