lvgl: Add logging settings to syscfg

LVGL has support for logs. This change allows to enable logs from mynewt syscfg. LV_USE_LOG - enables logs LV_LOG_LEVEL - allows to choose logging level LV_LOG_PRINTF - redirects logs to use printf (default for now, can be change latter to use mynewt logging) Signed-off-by: Jerzy Kasenberg <jerzy.kasenberg@codecoup.pl>
