wct4xxp: Moving the transmit short detection behind debug module param. This needs some more testing before it's on by default. If the card is otherwise functioning, these messages may be confusing to the user. If the card is not functioning, the driver can be reloaded with debug to check for this condition.

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

* This looks a little weird.

* There are only 8 physical ports on the TDM/AEX800, but the code immediately
* below sets 24 modules up. This has to do with the altcs magic that allows us
* to have single-port and quad-port modules on these products.
* The variable "mods_per_board" is set to the appropriate value just below the
* next code block.
*
* Now why this is important:
* The FXS modules come out of reset in a two-byte, non-chainable SPI mode.
* This is currently incompatible with how we do things, so we need to set
* them to a chained, 3-byte command mode. This is done by setting the module
* type to MOD_TYPE_FXSINIT for a little while so that cmd_dequeue will
* initialize the SLIC into the appropriate mode.
*
* This "go to 3-byte chained mode" command, however, wreaks havoc with HybridBRI.
*
* The solution:
* Since HybridBRI is only designed to work in an 8-port card, and since the single-port
* modules "show up" in SPI slots >= 8 in these cards, we only set SPI slots 8-23 to
* MOD_TYPE_FXSINIT. The HybridBRI will never see the command that causes it to freak
* out and the single-port FXS cards get what they need so that when we probe with altcs
* we see them.
