usb: fixes for v3.9-rc3

Browse Source 
Most fixes are on 'musb' driver. There's a sparse warning
 fix which marks omap2430_glue as static, a build warning
 fix which was found with randconfig, a fix for omap_musb_mailbox
 check and removal of 'select' from musb's Kconfig to prevent
 Kconfig warnings.
 
 Other than that, pxa25x got a fix which was introduced by the
 latest conversion to udc_start/udc_stop patchset, kernel-doc
 warnings for composite layer  and dwc3 got a build fix on
 sparc64.
