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 f4053874 (USB: MUSB:
fix kernel WARNING/oops when unloading module
in OTG mode).
Signed-off-by: NFelipe Balbi <balbi@ti.com>

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.

we don't need to enable IRQs until we have
a gadget driver loaded and ready to work,
so let's delay IRQ enable to ->udc_start()
and IRQ disable to ->udc_stop().

While at that, also move the related use of
request_irq() and free_irq().
