[PATCH 4/4] [RFC] ARM: treewide: manually change more mach-*/*.h includes

These are lots of device drivers that include machine

new ones.

And you end up missing a bunch of drivers in the process, such as the
sa1100 RTC driver which is shared between sa11x0 and PXA.  I wonder
how many of the Samsung platforms get broken by this as well...

In any case, what we _should_ be doing here as well is moving the headers
included by drivers for platform data out of the arch/arm/mach/ subtrees
and into include/linux/platform_data.  That will substantially reduce the
amount of mach/ headers to deal with.

Where I want this to get to is not a persistence of the existing crappy
situation where platforms stuff platform data definitions into arch/arm,
but instead put them in the right place.  That means providing them with
a good reason why the existing solution won't work, and not allowing
mach/ includes in drivers is a very good way to achieve that.
