[ARM] 3739/1: genirq updates: irq_chip, add and use irq_chip.name

Patch from David Brownell

ARM genirq cleanups/updates:

    - Start switching platforms to newer APIs
        * use "irq_chip" name, not "irqchip"
        * providing irq_chip.name

    - Show irq_chip.name in /proc/interrupts, like on x86.

This update a bit more than half of the ARM code.  The irq_chip.name
values were chosen to match docs (if I have them) or be otherwise
obvious ("FPGA", "CPLD", or matching the code).
