[IA64] fix NULL pointer in ia64/irq_chip-mask/unmask function
This patch fixes boot failure because irq_desc->mask() is NULL.
- Added mask/unmask functions to ia64's irq desc function table.
- rename hw_interrupt_type to irq_chip. hw_interrupt_type is old name.
- Tony: Added same change to arch/ia64/sn/kernel/irq.c as pointed out
by Eric Biederman ... mask/unmask functions there can be no-op.
