Ken Van Hoeylandt f9453d8956 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`

# AXP2101 power management IC
A driver for the X-Powers `AXP2101` PMIC: DCDC1-5 and ALDO1-4/BLDO1-2/CPUSLDO/DLDO1-2
enable and voltage control, battery/VBUS voltage readback, charge enable/status, and
system power off. Registers as a `power-supply` child device (voltage, is-charging,
charge control, power off) alongside its own public API for full rail control.
Also includes `axp2101-backlight`: a `BACKLIGHT_TYPE` driver for a backlight wired to one of
the AXP2101's LDOs, declared as a devicetree child node of the `axp2101` device it dims. Its
`ldo`, `min-millivolt` and `max-millivolt` properties select the channel and map the 0-255
brightness level onto that LDO's voltage range; brightness level 0 disables the LDO outright.
