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.
