wctdm24xxp: Add optional FXO digital loopback if DEBUG is defined.

Browse Source 
This module parameter will allow patgen/pattest to be used only on FXO
ports. *ALL* FXO ports will be placed in digital loopback mode when
set.

The current intent is for this to be removed as an optional module
parameter when there is a channel by channel representation in sysfs.
Otherwise, a new IOCTL would have to be defined and a tool written in
order to support this. DAHDI-696.
