usb: fixes for v3.12-rc4

Browse Source 
Here are some more fixes to musb's OTG support and a regression
 caused on latest merge window; pxa25x_udc and gpio-vbus learned
 to cope with deferred probe; s3c-hsotg got a fix for non-periodic
 endpoints write size and f_fs got an error handling fix for cases
 where ffs_do_descs() fail.
