Use the wrapper function for retrieving the platform data instead of
accessing dev->platform_data directly.

0848c94fb4 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.

6090885597 mfd: Fix return type of lm533 attribute is_visible
Since commit 587a1f1659 ("switch ->is_visible() to returning umode_t")
the return type of is_visible is umode_t rather than mode_t.

This silences a compiler warning on some architectures where these types
are not compatible.
