msm: thermal: Apply frequency limit on online CPU to LMH DCVSh
KTM won't apply a frequency mitigation request for an offline cluster.
Instead when the CPU is brought back online, the cpufreq will ask for
new request and KTM will limit the frequency at that time. With the LMH
DCVSh doing the frequency mitigation, the frequency request is not
applied when the CPU comes back online.
For targets with LMH DCVSh frequency mitigation, apply the latest
frequency mitigation request when the CPU comes back online.
