Two types of intr_map_data are supported:
INTR_MAP_DATA_GPIO and INTR_MAP_DATA_FDT.

This way interrupts can be allocated using the userspace gpio
interrupt allocation method, as well as directly from simplebus.
The latter can be used by devices that have its irq routed to a GPIO pin.

This is needed for an armv8 specific driver, that will inherit from this

used in interrupt filter context.

Fix locking in qoriq_gpio

qoriq_gpio_pin_setflags() locks the device mutex, as does
qoriq_gpio_map_gpios(), causing a recursion on non-recursive lock. This
was missed during testing for 16e549ebe.

Summary:
They're nearly identical, so don't use two copies. Merge the newer
