genirq: Implement irq_set_handler_locked()/irq_set_chip_handler_name_locked()
The main use case for the exisiting __irq_set_*_locked() inlines is to
replace the handler [,chip and name] of an interrupt from a region
which has the irq descriptor lock held, e.g. from the irq_set_type()
callback. The first argument is the irq number, so the functions need
so perform a pointless lookup of the interrupt descriptor for those
cases which have the irq_data pointer handy.
Provide new functions which take an irq_data pointer instead of the
interrupt number, so the lookup of the interrupt descriptor can be
avoided.
