perf: arm_pmu_acpi: Get rid of the edge-triggered interrupt oddity

The ACPI spec bizarrely indicates that the PMU interrupt can be
edge-triggered, which contradicts the very basics of the PMU
architecture (SW is required to clear the interrupt condition for
the level to drop).

Remove the code parsing this flag and always flag the interrupt
as level triggered, no matter what firmware says.
