wimax: allow specifying debug levels as command line option
Add "debug" module options to all the wimax modules (including drivers) so that the debug levels can be set upon kernel boot or module load time. This is needed as currently there was a limitation where the debug levels could only be set when a device was succesfully enumerated. This made it difficult to debug issues that made a device not probe properly. Signed-off-by: Inaky Perez-Gonzalez <inaky@linux.intel.com>
