arm64: dts: qcom: sm8250: Disable the not yet supported cluster idle state

Browse source 
[ 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.

vreg_l11c_3p3: failed to enable: -ETIMEDOUT

qcom-rpmh-regulator: probe of 18200000.rsc:pm8150l-rpmh-regulators failed with error -110
