Wait until we have de-bounced the presence of battery before moving on the
check for changes in polarity. This removes the sometimes random
polarity messages generated on an FXO port when the far side drops
battery from a supervisor disconnect.

Use the newly create bg_create and bg_join to actually probe / configure
groups of 4 modules in parallel. This currently has to be done in groups
of four due to the way 4-port modules are identified relative to single
port modules.
This provides a dramatic improvement in driver load time. When loading a
single TDM2400 with 24 FXS ports before this change:
# time modprobe wctdm24xxp vpmsupport=0
real 0m46.674s
user 0m0.000s
sys 0m0.520s
And after this change:
# time modprobe wctdm24xxp vpmsupport=0
real 0m7.900s
user 0m0.000s
sys 0m0.070s
Note that the boards themselves are still configured serially. Board
configuration can be parallelized once the assignment of board position
is moved out of the function that is run in parallel. Otherwise it could
be possible for board numbers to switch on repeated loads.

r10006 "wctdm24xxp: Add 'fastpick' module parameter." copied the
fast-off hook module parameter from the wctdm.c driver, but the setting
in that driver does not match the data sheet. The previous commit did
not actually change any of the significant bits in that register. Also,
that commit changed the timer, but did not disable the callibration
delay which is necessary for Type-II callerid.
The fastpickup option in the wctdm24xxp driver should now match the
fastpickup option in the wctdm driver.

If an FXS port is configured to use kewl start signalling, when the FXS port
is "hungup" it should drop battery for 500ms so that any attached devices can
detect that the remote side has disconnected. The wctdm24xxp driver
since version 2.4.0 was only dropping battery for ~5-10 ms because it would
set "open" on the line, but then the next time it read the line feed register
state, it was setting the LINE feed register to the idle state.
This change checks if the line is forced open before setting the FXS port back
"onhook" so as to not turn on battery prematurely.
This fixes a regression introduced in r9070 "wctdm24xxp: Prevent FXS Proslic
staying in "Forward/Reverse OnHookTransfer...". DAHDI-849.
Checking for open on the line feed registered was originally suggested by Alec
Davis.

We can already use the module type to determine presence of a module to
check. This also moves the background polling of the modules until after
the board is completely initialized because the module type may change
while the different types are being probed. This also means that we need
to preset the shadow registers for the FXS because otherwise the shadow
register will not have been read before the first time it's checked for
a power alarm.

Part of increasing system startup speed.
Splitting these two operations facilitate checking if there is a module
present synchronously on driver load from the actual load of the firmware and
configuration of the channels.
This will allow the presence of the VPM module to be flagged on the span
before registration, but load and configuration can happen in the background.
When the modules are eventually loaded via udev, there will be enough time
from the time the drivers are loaded to when dahdi_cfg will run to complete
the firmware load, eliminating the need to block the driver here.
