fbdev: Support for byte-reversed framebuffer formats
Allow generic frame-buffer code to correctly write texts and blit images for
1, 2 and 4 bit per pixel frame-buffer organizations when pixels in bytes are
organized to in opposite order than bytes in long type.
Overhead should be reasonable. If option is not selected, than compiler
should eliminate completely all overhead.
The feature is disabled at compile time if CONFIG_FB_CFB_REV_PIXELS_IN_BYTE is
not set.
[adaplas]
Convert helper functions to macros if feature is not enabled.
