This patch drops the powerpc-specific irq_host structures and uses the common
irq_domain strucutres defined in linux/irqdomain.h. It also fixes all
the users to use the new structure names.
Renaming irq_host to irq_domain has been discussed for a long time, and this
patch is a step in the process of generalizing the powerpc virq code to be
usable by all architecture.
An astute reader will notice that this patch actually removes the irq_host
structure instead of renaming it. This is because the irq_domain structure
already exists in include/linux/irqdomain.h and has the needed data members.

Add a 5121-custom reject if an input-only pin is requested to be output
(see 18.3.1.1 in the refman). Also, rewrite mach-specific quirk setup to
consume less lines which scales better.

Interrupt handler in MPC8xxx GPIO driver is missing the call to PIC EOI
(end of interrupt) handler. As a result, at least on 85XX systems, GPIO
interrupt is delivered only once. This patch adds the missing EOI call.
Tested on custom P1022 board.

Support MPC85xx platforms outside of MPC8572/MPC8536. The
MPC8572/MPC8536 have an erratum that is worked around based on having
"fsl,mpc8572-gpio" in the compatiable list. All other MPC85xx SoCs
don't require this workaround and thus utilize the 'fsl,pq3-gpio'
compatiable.

Move the driver to the place where it is expected to be nowadays. Also
rename its CONFIG-name to match the rest and adapt the defconfigs.
Finally, move selection of REQUIRE_GPIOLIB or WANTS_OPTIONAL_GPIOLIB to
the platforms, because this option is per-platform and not per-driver.
