OPP: Add support for config_regulators() helper
Extend the dev_pm_opp_set_config() interface to allow adding config_regulators() helpers. This helper will be called to set the voltages of the regulators from the regular path in _set_opp(), while we are trying to change the OPP. This will eventually replace the custom set_opp() helper.

Setting an hint is clearly not a guarantee and for these PMU interrupts an affinity hint, which is supposed to guide userspace for setting affinity, is beyond pointless, because the affinity of these interrupts cannot be modified from user space. Aside of that the error checks are bogus because the only error which is returned from irq_set_affinity_hint() is when there is no irq descriptor for the interrupt number, but not when the affinity set fails. That's on purpose because the hint can point to an offline CPU. Replace the mindless abuse with irq_set_affinity().

Let's refactor the frame. Two new callbacks are added for the HW accessors: * hisi_uncore_ops::get_int_status returns a bitmap of events which have overflowed and raised an interrupt * hisi_uncore_ops::clear_int_status clears the overflow status for a specific event These callback functions are used by a common IRQ handler, hisi_uncore_pmu_isr(). One more function hisi_uncore_pmu_init_irq() is added to replace each PMU initialization IRQ interface and simplify the code.
