lib: sbi_pmu: move pmu irq information into pmu itself
Don't spread checking for pmu extensions through the code
but instead introduce a sbi-pmu function that other code can
call to get the correct information about the existence of the
pmu interrupt.
Add a sbi_pmu_device override function to allow overridung this
bit as well if needed.
