[PATCH 1/2] atmel_lcdfb: Set ypanstep to 1 and enable y-panning on AT91

[Stanislaw Gruszka <stf_xl@wp.pl>]

Panning in the y-direction can be done by simply changing the DMA base
address. This code is already in place, but FBIOPAN_DISPLAY will
currently fail because ypanstep is 0.

Set ypanstep to 1 to indicate that we do support y-panning and also
set the necessary acceleration flags on AT91 (AVR32 already have
them.)
