The NOP OTG transceiver driver needs to be usable from modules.
Make sure its symbols are always accessible at both compile and
link time, and make sure the device instance is allocated from
the heap so that device lifetime rules are obeyed.

NOP transceiver is used by all the usb transceiver which are mostly
autonomous and doesn't require any programming or which are built
into the usb ip itself.NOP transceiver only allocates the memory
for struct xceiv and calls otg_set_transceiver() so function call
to otg_get_transceiver() will return a valid transceiver.
NOP transceiver device should be registered by calling
usb_nop_xceiv_register() from platform files.

Call usb_gadget_vbus_connect() and ...disconnect() from a
workqueue rather than from an irq handler, allowing msleep()
calls in vbus_session. Update kerneldoc to match.

As Russell King points out, calling put_device(otg_transceiver->dev)
directly in driver cleanup paths makes assumptions about otg_transceiver
internals.

For the header files in include/linux/usb, add missing multiple
inclusion protection and standardize what's already there. The
apparent standards:
* macro name of __LINUX_USB_headerfile_H
* inclusion protection placed after leading comment block
* macro name added as a comment on the final #endif
* any obvious trivial whitespace cleanup associated with the above
