lcd drivers: Convert lcd_[remote_]framebuffer to a pointer

Browse source 
Change all lcd drivers to using a pointer to the static framebuffer
instead of directly accessing the static array. This will let us
later do fun things like dynamic framebuffer sizes (RaaA) or
ability to use different buffers for different layers (dynamic
skin backdrops!)
