cfadd83852 powerpc/8xxx: Fix interrupt handling in MPC8xxx GPIO driver
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.

15a5148c6f powerpc/85xx: Add 'fsl,pq3-gpio' compatiable for GPIO driver
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.

c68308dd50 gpio: move mpc8xxx/512x gpio driver to drivers/gpio
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.
