genirq: Change hwirq parameter to irq_hw_number_t
The irqdomain implementation internally represents hardware IRQs as
irq_hw_number_t, which is defined as unsigned long int. When providing
an irq_hw_number_t to the generic_handle_domain() functions that expect
and unsigned int hwirq, this can lead to a loss of information. Change
the hwirq parameter to irq_hw_number_t to support the full range of
hwirqs.
