mfd: stmpe: Support gpio over irq under device tree
The stmpe_platform_data has a irq_over_gpio field, which allows the
system to read STMPE events whenever an IRQ occurs on a GPIO pin.
This patch adds the ability to configure this field and to use a GPIO
as an IRQ source for boards configuring the STMPE in device tree.

mfd: stmpe: mask off unused blocks properly
The STMPE driver would just read/modify/write the system control
register on the STMPE1601, meaning it would not properly mask off
the PWM block, which remained active if it was on at boot time.
This makes sure the blocks are always masked off if they were
active on boot, saving some power. Also rename the inconsistenty
named STMPE1601 define for the PWM block activation.

mfd: Prevent STMPE from abusing mfd_add_devices' irq_base parameter
Originally IRQ incrementers were provided in some template resource
structures for keypad and touchscreen devices. These were passed as
IORESOURCE_IRQs to MFD core in the usual way. The true device IRQs
were instead added to the irq_base when mfd_add_devices was invoked.
This is clearly an abuse of the call, and does not scale when IRQ
Domains are brought into play. Before we can provide the STMPE with
its own IRQ Domain we must first fix this. This patche keeps most
of the driver's structure, keeping the template strategy. However,
instead of providing the IRQ as an increment to irq_base, we
dynamically populate the IORESOURCE_IRQ with the correct device IRQ.

mfd: core: Push irqdomain mapping out into devices
Currently the MFD core supports remapping MFD cell interrupts using an
irqdomain but only if the MFD is being instantiated using device tree
and only if the device tree bindings use the pattern of registering IPs
in the device tree with compatible properties. This will be actively
harmful for drivers which support non-DT platforms and use this pattern
for their DT bindings as it will mean that the core will silently change
remapping behaviour and it is also limiting for drivers which don't do
DT with this particular pattern. There is also a potential fragility if
there are interrupts not associated with MFD cells and all the cells are
omitted from the device tree for some reason.
Instead change the code to take an IRQ domain as an optional argument,
allowing drivers to take the decision about the parent domain for their
interrupts. The one current user of this feature is ab8500-core, it has
the domain lookup pushed out into the driver.
