Mainly, this involves two changes:
1) xilinx->xlnx (recognized standard is to use the stock ticker)
2) In order to have the device tree focus on describing what the
hardware is as exactly as possible, the compatible strings contain the
full IP name and IP version.

Some custom implementations of the xilinx fb can use resolutions other
than 640x480.  This patch allows the resolution to be specified in the
device tree or the xilinx_platform_data structure.

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.

Split the device setup code away from the platform bus binding.  This is

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

change printk calls to the appropriate dev_*() call.
