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.

Minor musb_hdrc updates:
- so it'll build on DaVinci, given relevant platform updates;
* remove support for an un-shipped OTG prototype
* rely on gpiolib framework conversion for the I2C GPIOs
* the <asm/arch/hdrc_cnf.h> mechanism has been removed
- catch comments up to the recent removal of the per-SOC header
with the silicon configuration data;
- and remove two inappropriate "inline" declarations which
just bloat host side code.
There are still some more <asm/arch/XYZ.h> ==> <mach/XYZ.h>
changes needed in this driver, catching up to the relocation
of most of the include/asm-arm/arch-* contents.

Fixes kernel panic while ISO IN transfer is aborted.Replaced
usb_hcd_unlink_urb_from_ep() from musb_giveback() to __musb_giveback()
to make sure urb is unlinked before giveback when __musb_giveback() is
called from musb_urb_dequeue().
Acquired musb->lock() before usb_hcd_unlink_urb_from_ep() within in
enqueue path.

Fixes enumeration failures when a USB device attached to a LS hub is
connected to OMAP EVM via HS hub. This is fixed by correctly
programming hub address register in enqueue path.

This patch adds support for MUSB and TUSB controllers
integrated into omap2430 and davinci. It also adds support
for external tusb6010 controller.
