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.
