Felipe Balbi 622859634a usb: musb: drop a gigantic amount of ifdeferry
the MUSB IP is always OTG, so there's no point
in adding so many ifdefs on the code. Drop those
and always compile the driver for OTG support.

This also allows us to drop the useless "driver
mode" choice. For doing that, we need to make
musb depend on both Host and Peripheral side.

Ajay Kumar Gupta a483d7068f 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.)

Ajay Kumar Gupta 23d15e070c usb: musb: fix BULK request on different available endpoints
Fixes co-working issue of usb serial device with usb/net devices while
oter endpoints are free and can be used.This patch implements the policy
that if endpoint resources are available then different BULK request goes
to different endpoint otherwise they are multiplexed to one reserved
endpoint as currently done.

Switch statement case is reordered in musb_giveback() to take care of
bulk request both in multiplex scenario and otherwise.

NAK limit scheme has to be added for multiplexed BULK request scenario
to avoid endpoint starvation due to usb/net devices.
