if CONFIG_OF is disabled, np will be unused

<linux/sizes.h> is the header defining SZ_4
and SZ_16M, we shouldn't depend on indirect
inclusion so let's explicitly include it.

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.

Those comments haven't been updated for a long
time, so much that they don't make sense anymore.
Best to remove them.

Add support for basic power management on
the dwc3 driver. While there is still lots
to improve for full PM support, this minimal
patch will already make sure that we survive
suspend-to-ram and suspend-to-disk without
major issues.

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().
