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.

irq_base of the tps65912 irq platform data should be
initialized with the board provided irq_base data.

We neglect to free init_data on successful exit. I also moved two
assignments to just before they are needed. This avoids doing them in
case we hit an earlier error exit from the function.

This module controls the interrupt handling for the tps65912.
The interrupt sources can be the following:
- GPIO
- PWRON signal
- PWRHOLD signal
- Temperature detection

The tps65912 chip is a power management IC. It contains the following
components:
- Regulators
- GPIO controller
The core driver is registered as a platform driver, it provides communication
through I2C and SPI interfaces.
