I've been working on some patches that allow suspending and resuming
the musb-dsps platform. This was tested for host mode only.

With these patches applied, I can successfully bring an AM335x board
to suspend with a USB media connected, and access it again after
resume. Note that this currently only works with CONFIG_MUSB_PIO_ONLY
set. The cppi41 driver needs some more love to make this work. I'll
work on that next.

Thanks,
Daniel
