genirq/generic-chip: Fix the irq_chip name for /proc/interrupts

Browse Source 
irq_init_generic_chip() only sets the name for the first chip type, which
leads to empty names for other chip types.  Eventually, these names will be
shown as "-" /proc/interrupts.

Set the name for all chip types by default.
