Enable offloading of display_write call to background thread for color displays. This feature is opt-in, as it may offer significant performance gains for every display pipeline. When enabled display_write and lv_disp_flush_ready will be called from a background thread. This means that while the display driver waits on the hardware to render the framebuffer, the LVGL rendering thread will not be blocked. Signed-off-by: Daniel DeGrasse <daniel.degrasse@nxp.com>
