Migrate devices, create drivers, other improvements & fixes (#574)

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`
