lib: sbi: pmu: fix usage of sbi_pmu_irq_bit()
While sbi_pmu_irq_bit() was used to delegate irq to S-mode, LCOFIP usage
was still hardcoded in various places. This led to change the returned
value of sbi_pmu_irq_bit() to be a bit number rather than a bit mask
since it returns an 'int' and we need to obtain the bit number itself to
handle it in the IRQs handlers. Add a similar function to return the
irq mask which can also be used where the mask is required rather than
the bit itself.
