atmel_lcdfb: fix initialization of a pre-allocated framebuffer
Fix initialization of framebuffer not calling ioremap_writecombine() function and not using internal SRAM for at91sam9rl. This is a little rework of the "Don't initialize a pre-allocated framebuffer" patch that corrects the call to ioremap_writecombine() function. It also cuts the use of internal SRAM for at91sam9rl : it is a bit small for a framebuffer.
