This is a preparatory patch to introduce Interrupt Message Store (IMS).

Until now, platform-msi.c provided a generic way to handle non-PCI MSI
interrupts. Platform-msi uses its parent chip's mask/unmask routines
and only provides a way to write the message in the generating device.

Newly creeping non-PCI complaint MSI-like interrupts (Intel's IMS for
instance) might need to provide a device specific mask and unmask callback
as well, apart from the write function.

Hence, introduce a new structure platform_msi_ops, which would provide
device specific write function as well as other device specific callbacks
(mask/unmask).

As this is not following the Intel-specific rules for sending me new
code, I am just deleting it all from my inbox.

That is my fault. As the aggregator of the patches, I should've signed off Megha's patches.


Please follow the rules you all have been given, they are specific and
there for a reason.  And in looking at this code, those rules are not
going away any time soon.
