Add ath_printk and ath_<level> similar to dev_printk and dev_<level> from device.h This allows a more gradual rename of ath_print to to ath_dbg or perhaps ath_debug. This basically removes debug.h leaving only an #define ath_printk ath_dbg there and moving all the ATH_DBG_<foo> enums to ath.h I do not think there's much purpose for struct ath_common * being passed to the ath_printk functions, but perhaps there might be.
