drivers/perf: hisi: Permit modular builds of HiSilicon uncore drivers
This patch lets HiSilicon uncore PMU driver can be built as modules.
A common module and three specific uncore PMU driver modules will be built.
Export necessary functions in hisi_uncore_pmu module, and change
irq_set_affinity to irq_set_affinity_hint to pass compile.
