Without this patch clearing was done only when U-Boot was compiled with
MUSB Host Controller. But clearing of data toggle bit is needed also for
MUSB Device Controller otherwise Device Controller does not work correctly.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

USB-related options are usually prefixed with CONFIG_USB and platform-specific
adaptation for the MUSB controller already have a CONFIG_USB_MUSB prefix, so
this switches all MUSB-related options to a CONFIG_USB_MUSB prefix, for
consistency.

AM35x supports only 32bit read operations so we need to have
workaround for 8bit and 16bit read operations.

MUSB PHY on OMAP3EVM Rev >= E uses external Vbus supply to support
500mA of power.We need to program MUSB PHY to use external Vbus
for this purpose.
Adding 'extvbus' member in musb_config structure which should be set
by all the boards where MUSB interface is using external Vbus supply.
Also added ULPI bus control register read/write abstraction for
Blackfin processor as it doesn't have ULPI registers.

The dynamic FIFO handling under MUSB is optional, and some parts (like
the Blackfin processor) do not implement support for it.
Due to this, the FIFO reading/writing steps need special handling, so
mark the common versions weak so drivers can override.

This change adds the usb device support for musb.
Omap3 platform support added at the same level as davinci.
The interface for usbtty to use the musb device support was added.
Verified on omap3 beagle, zoom1 and zoom2.
