libpayload: cbgfx: Clear screen by sequential access
Currently clear_screen() calls set_pixel() to set all pixels. However,
the actual order of pixels being set depends on the framebuffer
orientation. With NORMAL orientation, the framebuffer is accessed
sequentially; with LEFT_UP/RIGHT_UP orientation, it is accessed back and
forth, leading to performance drop (>1 second on bugzzy).
Therefore, ensure sequential access to the framebuffer, regardless of
the orientation.
