Vladimir Zapolskiy e4e6448638 cpufreq: qcom-cpufreq-hw: Clear dcvs interrupts
It's noted that dcvs interrupts are not self-clearing, thus an interrupt
handler runs constantly, which leads to a severe regression in runtime.
To fix the problem an explicit write to clear interrupt register is
required, note that on OSM platforms the register may not be present.
