HID: add framebuffer support to PicoLCD device
Add framebuffer support to PicoLCD device with use of deferred-io. Only changed areas of framebuffer get sent to device in order to save USB bandwidth and especially resources on PicoLCD device or allow higher refresh rate for a small area. Changed tiles are determined while updating shadow framebuffer. Signed-off-by: Bruno Prémont <bonbons@linux-vserver.org> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
