Moved global variable "musb_debugfs_root" and static variable
"old_state" to 'struct musb' to help support multi instance of
musb controller as present on AM335x platform.
Also removed the global variable "orig_dma_mask" and filled the
dev->dma_mask with parent device's dma_mask.

There's really no point in doing all that
initcall trickery when we can safely let
udev handle module probing for us.
Remove all of that trickery, by moving everybody
to module_init() and making proper use of
platform_device_register() rather than
platform_device_probe().

seq_files use the private_data field of a file struct for storing a seq_file structure,
data should be stored in seq_file's own private field (e.g. file->private_data->private)
Otherwise seq_release() will free the private data when the file is closed.

DMA_ADDR and DMA_COUNT are 32-bit registers, not 16-bit.
Marking them as 16-bit in the table causes only the lower
16-bits to be dumped and this is misleading.

Implicit slab.h inclusion via percpu.h is about to go away. Make sure

when we fail to probe(), we can call musb_exit_debugfs().
Allow that by removing section annotations.

for now only a simple register dump entry (which can
be rather useful on debugging) and a way to start
test modes.
