The call to xilinxfb_assign is getting unwieldy when adding features
to the Xilinx framebuffer driver.  Change xilinxfb_assign() to accept
a pointer to a xilinxfb_platform_data structure to prepare for adding
additition configuration options.

Missing pdata structure is not a fatal error.  The device can still be
initialized without it.

Adds the of_platform bus binding to the xilinxfb driver.  Needed to
use framebuffer devices described in the OF device tree (used by
arch/powerpc).

Split the device setup code away from the platform bus binding.  This is
in preparation for adding the of_platform bus binding to this driver and
most of the setup code is common between the two busses.

Labels and gotos are used in xilinxfb_assign to unwind allocations
on device registration failures.  Rename the labels to reflect the
error which occured.  This change is being made to make it easier
to add new failout paths (which occurs in a subsuquent patch) and
to make reviewing the failout path easier.

The dev_dbg, dev_err, etc functions provide more context that plain
vanilla printk which is useful for debugging.  Where appropriate,
change printk calls to the appropriate dev_*() call.

XilnixFB can be used by more than just arch/ppc.  Move the data structure
definition into include/linux/xilinxfb.h so it can be used by microblaze
and arch/powerpc

Lack of pdata is not a fatal omission.  The driver can still be used even
if we do not know the screen dimensions.
