V4L/DVB (5884): zr36067: clean up debug function
Debugging cleanups to the zr36067 driver:
* Use module_param_named() to declare the debug parameter, so we can
use a single global variable to handle the debug level. This makes
the driver a bit smaller (by 648 bytes on x86_64), thanks to one
less level of indirection on every use.
* Change the debug parameter sysfs permissions, so that the debug
level can be adjusted at runtime, as is done in many other
media/video drivers.
* The debug level is between 0 and 5, not 0 and 4.
* Move the zr_debug export and dprintk macro definition to a header
file so that we don't have to define them in each source file.
* Simplify a duplicate test on zr_debug.
Note that zr_debug was subsequently renamed to debug_zr36067 to avoid
possible conflicts with other Zoran device drivers, on a suggestion
by Trent Piepho.
