usb: fixes for v3.15-rc3

Quite a few fixes this time since I lost v3.15-rc2
window.

Most fixes are MUSB which learned to remove its debugfs directories
properly, got a fix for PHY handling and now knows that it should
make sure its clocks aren't gated before trying to access registers.

ffs got a race fix between ffs_epfile_io() and ffs_func_eps_disable().

dwc3 got a fix for system suspend/resume and now only iterates over
valid endpoints when trying to resize TX fifos.

usb_get_phy() now will properly return an error if try_module_get() fails.

We also have a revert for a NAPI conversion on the ethernet gadget which
was causing a kernel BUG.
