* Removed work queue for maint interface as it is not needed in this driver
* Error counters are now accessible through the maint interface
* Consolidated and revised the big maint switch case
* Added loopup/loopdown code transmit logic to E1
* Now supports error/defect insersion

The framer appears to continue transmitting a signal after modprobe -r. This
patch will leave the physical framer reset pin asserted to force the chip to
stop transmitting a signal when there is no driver attached.

Removed all the custom logic and replaced with the common platform wcxb stuff.
There are also changes in here to standardize the function prefix in this
driver to t13x_.

Now uses framer interrupt vector polling (in the FPGA interrupt) for
alarm, loopcode, and signaling events eliminating continuous polling.
Now uses timer function for alarm and loopcode debouce, which only
executes during exception conditions.

The octasic library is relatively large and is currently separately linked into
both the wcte13xp and wct4xxp libraries. This change moves it out into a
separate loadable module.
The bigest change from the drivers perspectives is that they must provide a
table of callbacks instead of using statically linked Oct6100UserXxxxx functions
to allow the library to communicate with actual parts on the cards.

With certain pci controllers that support pci hotplug, during the reset
sequence of the fpga, the host controller can get confused about the state of
the card and throw an nmi.
Known affected systems:
HP proliant DL160 & DL360p
Dell poweredge R520
Super Micro X7SPA-HF
This patch attempts to work around that by removing the fpga reset sequence
from the driver startup, then setting various control registers to known
starting state values.
This patch removes the field upgradeable firmware logic temporarily for the
te133 card to prevent fpga reset.

This was causing inconsistancies with dahdi_scan showing an "UNCONFIGURED" span
in the "RED" state.
