Convert some MIPS architecture's code to using struct syscore_ops
objects for power management instead of sysdev classes and sysdevs.

This simplifies the code and reduces the kernel's memory footprint.
It also is necessary for removing sysdevs from the kernel entirely in
the future.

Scripted with coccinelle.

The conversion did not make use of the new chip flag which signals the
core code to mask the chip before calling the set_type callback. Sigh.
Use the new lockdep helper as well.

Currently there is one irq_chip per gpio_chip with the only difference
being the name. Since the information whether the irq belong to GPIO
bank A, B, C or D is not that important rewrite the code to simply use
a single irq_chip for all gpio_chips.
