Analyze and document the t6963 driver:
* Add Doxygen comments (also for internal functions, shortened for API). * Document initialization. * Remove some unused variables and defines. * Pass through indent. * Remove references to LCD pins from documentation and add some warning.

Displays using T6963 chipset come in a variety of pin-outs and power configurations.
|

They usually require negative voltage for contrast and some displays have
|
||||
a negative voltage generator onboard. Therefore the wiring table below does
|

only list signal names, not LCD pins. Be sure to get the correct datasheet
|

for your display and identify the pins to use!
