Merge branch irq/print_chip into irq/irqchip-next

* irq/print_chip:
  : .
  : Convert irqchip drivers that use the .name field as a topology
  : description to the .irq_print_chip callback, which allows the
  : name to be made dymanic. The irq_chip structures are then made
  : 'const' in order to prevent further abuse.
  : .

  irqchip/lpc32xx: Switch to dynamic chip name output
