Use the wrapper function for retrieving the platform data instead of
accessing dev->platform_data directly. This is a cosmetic change
to make the code simpler and enhance the readability.

Use vm_iomap_memory() instead of [io_]remap_pfn_range().
vm_iomap_memory() gives us much simpler API to map memory to userspace,
and reduces possibilities for bugs.

CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
markings need to be removed.
This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.
Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

Convert the sa11x0 framebuffer driver to obtain the base address of its
hardware registers from the platform resources, and ioremap this rather
than relying on the static mappings.

The GPIO set and clear registers should only be written, rather than
read, modified, and written. A read-modify-write will have undesired
side effects.

The sa1100fb driver needs to set the GPIO direction and alternate
function register according to the panel that we're driving. We've
done this in the driver by read-modify-writing the register, which
may cause problems with races. Fix this with a minimal change.

Now that the LCD information is available while the driver is loaded,
we don't need to cache that information into our driver private data
structure. Get rid of it.

Remove the assabet specific initialization for PAL output mode -
we call the lcd_power function before we enable the LCD controller,
which will disable the LCD panel to prevent it receiving incorrect
timings. Therefore, this setup here is redundant.

Since commit [e58aa3d2: genirq: Run irq handlers with interrupts disabled],
We run all interrupt handlers with interrupts disabled
and we even check and yell when an interrupt handler
returns with interrupts enabled (see commit [b738a50a:
genirq: Warn when handler enables interrupts]).
So now this flag is a NOOP and can be removed.

As suggested by Andrew Morton, remove memzero() - it's not supported
on other architectures so use of it is a potential build breaking bug.
Since the compiler optimizes memset(x,0,n) to __memzero() perfectly
well, we don't miss out on the underlying benefits of memzero().
