Matias N 5bcaeff541 lvgl: use malloc/free for memory handling and "tickless" tick interface 
This makes LVGL use malloc/free to handle its memory (instead of
their own memory handling) and supports a tick interface by which
LVGL can ask NuttX the elapsed time, instead of having to periodically
"tick" LVGL internal time in a thread.
