atmel_lcdfb: add board parameter specify framebuffer memory size
Specify how much physically continuous, DMA capable memory will be
allocated at driver initialization time. This allow to create framebuffer
device with larger virtual resolution. Combine with y-panning this can be
used to implement double buffering acceleration method.
