[PATCH] USB: musb: fix warnings in Blackfin regs

[Mike Frysinger <vapier@xxxxxxxxxx>]

The recent commit "usb: musb: Add context save and restore support" added
some stubs for the Blackfin code so things would compile, but it also
added a bunch of warnings due to missing return statements.

Note: this should be merged for 2.6.34 as it's a regression to 2.6.33
