wctdm24xxp: Add 'fastpick' module parameter.

Browse Source 
When true / 1 the FXO port will use a shorter off-hook calibration
delay. This is sometimes necessary in order to properly decode Type-II
Caller ID information which is sent shortly after an FXO port goes off
hook.

Defaults to 0 unless opermode is "JAPAN" then it will default to 1. This
functionality was ported from the wctdm.c driver.

DAHDI-854.
