drm/fb: Don't expose mmio for fbdev emulation layer
For the fbdev api if the struct fb_var_screeninfo accel_flags field is set to FB_ACCELF_TEXT then userland applications can not mmap the mmio region. Since it is a bad idea for DRM drivers to expose the mmio region via the fbdev layer we always set the accel_flags to prevent this. Please apply.
