ath5k: Port debug.c over to the new band API and enable as build option

This patch finishes the port and enables debug as an build option.
This was tested on:

Atheros AR5213A chip found (MAC: 0x59, PHY: 0x43)
RF5112A multiband radio found (0x36)

Note:

For 2 GHz band on the above card I noticed we get negative channel
numbers. Will look into this unless someone beats me to it.

Example out put when loading using:

sudo modprobe ath5k debug=0x00000400
