drivers/perf: arm_pmu: rename irq request/free functions
For historical reasons, portions of the arm_pmu code use a cpu_pmu_ prefix rather than an armpmu_ prefix. While a minor annoyance, this hasn't been a problem thusfar. However, to enable ACPI support, we'll need to expose a few things in header files, and we should aim to keep those consistently namespaced. In preparation for exporting our IRQ request/free functions, rename these to have an armpmu_ prefix. For consistency, the 'cpu_pmu' parameter is also renamed to 'armpmu'.
