usb: fixes for v3.16-rc4

Browse source 
A few more fixes for this RC cycle. There's a revert of a previous patch
 which ended up being the wrong version, so we reverted that commit and
 applied a better fix.
 
 CPPI41 got a race condition fix which was found by Thomas Gleixner.
 
 The MSM PHY driver got a runtime pm usage fix so that it wouldn't
 kill the PHY while it was still being used.
 
 We also have a fix for a panic caused when removing musb_am335x driver.
 
 Other than that, a few other minor fixes.
