[RFC/RFT] OMAP: N770: remove custom implementation of ads7846_get_pendown_state

[Dmitry Torokhov <dmitry.torokhov@gmail.com>]

The default implementation matches exactly our custom one so we can switch
to using the default one. As a bonus the driver will take care of setting
GPIO line for us.

No hardware so not tested...

Thanks!
