if we initialize gadget->dev.driver ourselves,
UDC drivers won't have to do the same, so we
can remove some duplicated code.

if udc-core always does it, we can delete
some extra lines from all UDC drivers. Besides,
it avoids mistakes from happening and propagating.

gadget's device pointer now is guaranteed to
have valid dma_mask, dma_parms and coherent_dma_mask
fields since we're always copying from our
parent device.

This driver can compile in any arch quite
easily by just removing a few headers and
dropping cpu_is_* check from module_init.

when commit 388e5c5 (usb: dwc3: remove dwc3
dependency on host AND gadget.) changed the
way debugfs files are created, it failed to
note that 'mode' is necessary in Dual Role
mode only while 'testmode' and 'link_state'
are valid in Dual Role and Peripheral-only
builds. Fix this while also converting pre-
processor conditional to C conditionals.

nobody should be modifying that structure and
debugfs has already being fixed to take const
arguments, so we won't cause any new compile
warnings.

whenever we grab an unknown link_state we
were printing the entire register value as
a integer but that's hardly useful; instead,
let's print only the bogus state value.

this function will receive enum usb_device_state
and return a human-readable string from it or,
case an unknown value is passed as argument,
the string "UNKNOWN".

by moving to threaded IRQs, we allow our IRQ
priorities to be configurable when running with
realtime patch. Also, since we're running in
thread context, we can call functions which
might sleep, such as sysfs_notify() without
problems.

those two glues are still including <mach/>
headers and no active developement has been
going on those glues for quite some time.
Apparently, for da8xx glue, only initial commit
3ee076de (usb: musb: introduce DA8xx/OMAP-L1x
glue layer) has been tested. All other patches
seem to have been compile-tested only.
For davinci glue layer, last real commit dates
back from 2010, with commit f405387 (USB: MUSB:
fix kernel WARNING/oops when unloading module
in OTG mode).

MUSB still needs lots of work on the DMA part
if we want to enable multiple DMA engines on
a multiplatform kernel. Meanwhile, we're forcing
PIO-only so that we, at least, have a working
driver.
