Migrated devices to kernel drivers: - guition-jc3248w535c - m5stack-core2 - m5stack-cores3 - m5stack-papers3 New drivers: - axp192-module - axp2101-module Fixes: - Fix SD card LDO for P4 devices - Updated PowerOff app to work with kernel displays - Fix for `lvgl_try_lock()` timing - Fix for touch events with slow updating displays Improvements: - `GuiService` now keeps trying to lock to prevent silent failures caused by drivers. - `GuiService` now uses lvgl-module calls for locking/unlocking - display driver now has capability `DISPLAY_CAPABILITY_SLOW_REFRESH`
