musb: add high bandwidth ISO support
Tested on OMAP3 host side with Creative (Live! Cam Optia) USB camera
which uses high bandwidth isochronous IN endpoints. FIFO mode 4 is
updated to provide the needed 4K endpoint buffer without breaking
the g_nokia composite gadget configuration. (This is the only
gadget driver known to use enough endpoints to notice the change.)
