[PATCH] fbdev: set a default access_align value

From: James Simmons <jsimmons@infradead.org>

Set the default access_align variable.  This variable tells us how much data
the hardware can handle in a single read/write cycle.  For example the epson
chipset can handle only 16 bit reads and writes to the framebuffer.
