atmel_lcdfb: set ypanstep to 1 and enable y-panning on AT91
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.)
