hpsa: add interrupt number to /proc/interrupts interrupt name
Add the interrupt number to the interrupt names that appear in /proc/interrupts, so they are unique Also, delete the IRQ and DAC prints. Other parts of the kernel already print the IRQ assignments, and dual-address-cycle support has not been interesting since the parallel PCI bus went from 32 to 64 bits wide.
