cpuidle: riscv-sbi: Add cpuidle_disabled() check
The consumer devices that inside the cpu/cluster power domain may register
the genpd notifier where their power domains point to the pd nodes under
'/cpus/power-domains'. If the cpuidle.off==1, the genpd notifier will fail
due to sbi_cpuidle_pd_allow_domain_state is not set. We also need the
sbi_cpuidle_cpuhp_up/down to invoke the callbacks. Therefore adding a
cpuidle_disabled() check before cpuidle_register() to address the issue.
