We shouldn't ever panic in a driver, and these calls were never being
used, so just delete them, as obviously the driver is working properly
now (right?)

Use the in-kernel pr_debug() calls instead of trying to roll your own

Now that no USB atm driver is relying on the CONFIG_USB_DEBUG option
(well, really the DEBUG option, thanks to some Makefile fun), remove it
from the Makefile.

Also remove two last vestiges of DEBUG in the usbatm.c driver, moving
one to VERBOSE_DEBUG, which no one ever really cares about, and the
other to use the dynamic debug subsystem.

Move the atm_dbg() call to use the dynamic debug subsystem, and not rely
on CONFIG_USB_DEBUG for if things should be printed out or not.

This also means the drivers do not have to be rebuilt to get debugging
messages, important for getting information from users who can not
rebuild their kernels.

Enable the USB atm drivers to use the dynamic debugging subsystem, and
not rely on if CONFIG_USB_DEBUG is enabled or not for debugging
messages. This also provides a saner debug message, pointing out the
exact device the message is coming from.

Remove the vendor and product module parameters which were added a long

new device ids (and which isn't limited to five new vid/pid pair).

A vid/pid pair can be added dynamically using sysfs, for example:

  echo 0451 1234 >/sys/bus/usb-serial/drivers/ti_usb_3410_5052_1/new_id

for 1-port adapters, or

Remove broken "chase" implementation which was supposed to be used to
drain the write buffers at break.

The chase implementation slept on a wait queue which was never woken up
(i.e. no hardware buffers were queried), and thus amounted to nothing
more than polling chars_in_buffer, something which has already been
taken care of by the tty layer.
