arm_pmu: simplify arm_pmu::handle_irq
The arm_pmu::handle_irq() callback has the same prototype as a generic IRQ handler, taking the IRQ number and a void pointer argument which it must convert to an arm_pmu pointer. This means that all arm_pmu::handle_irq() take an IRQ number they never use, and all must explicitly cast the void pointer to an arm_pmu pointer. Instead, let's change arm_pmu::handle_irq to take an arm_pmu pointer, allowing these casts to be removed. The redundant IRQ number parameter is also removed.
