Impact: cleanup
Unify pmd_pfn. Unfortunately it can't be demacroed because it has a
cyclic dependency on linux/mm.h:page_to_nid().

This kernel symbol provides a way for drivers to switch on alternate
function for a certain GPIO pin. Turning it off is done implicitly when
changing the GPIO direction, as that would be fixed when using the given
pin als alternate function.

As rb532_dev3_ctl_res is not used by any platform device, it can be dropped
when not used for holding the physical address of the device 3 controller.
Also a size of one byte should suffice when ioremapping the physical
address mentioned above, as only a single byte is being read from and
written to it.

This code doesn't belong to gpio.c, as it's completely unrelated to

The data to be written is just a byte, so use writeb instead of writel.
Also, dev3.base contains the address, not the data so referencing here
is wrong.

As the pata-rb532-cf driver calls gpio_direction_input(), the calls to
rb532_gpio_set_func() and rb532_gpio_direction_input() are not needed since
the alternate function is automatically being disabled when changing the
GPIO pin direction.
The later two calls to rb532_gpio_set_{ilevel,istat}() are implicitly being
done by the IRQ initialisation of pata-rb532-cf.

When a driver calls gpio_set_direction_{input,output}(), it obviously
doesn't want the alternate function for that pin to be active (as the
direction would not matter in that case). This patch ensures alternate
function is disabled when the direction is being changed.

Interrupt Group 4 mapps the GPIO pins enabled as interrupt sources;
add defines to make this clear when addressing them later in code.
The mapped GPIOs support triggering on either level high or low. To
achieve this, the set_type() function calls rb532_gpio_set_ilevel() for
interrupts of the above mentioned group.
As there is no way to alter the triggering characteristics of the other
interrupts, accept level triggering on status high only. (This is just a
guess; but as the system boots fine and interrupt-driven devices (e.g.
serial console) work with no implications, it seems to be right.)
To clear a GPIO mapped IRQ, the source has to be cleared (i.e., the
interrupt status bit of the corresponding GPIO pin). This is done inside
rb532_disable_irq().
After applying these changes I could undo most of my former "fixes" to
pata-rb532-cf. Particularly all interrupt handling can be done
generically via set_irq_type() as it was before.

The algorithm works unconditionally. If bitval is one, the first line is
a no op and the second line sets the bit at offset position. Vice versa,
if bitval is zero, the first line clears the bit at offset position and
the second line is a no op.

If a context switch occurred between the watch exception and reading the
watch registers, it would be possible for the new process to corrupt their
