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.

Graphics / lvgl LVGL

Usage

Import with #include <lvgl/lvgl.h> or #include <lvgl.h>.

Upstream example ported to NuttX is present at examples/lvgldemo.

LVGL can be used with framebuffer device. To find example boards with this preconfigured, search for CONFIG_GRAPHICS_LVGL=y in defconfig files. All of them have also CONFIG_VIDEO_FB=y present.

As a second option, LVGL can talk to a display driver and explicitly draw line by line. For this case, there is no preconfigured board present. Go to Porting section of upstream documentation for more hints.
