New kernel drivers and device implementation updates (#561)

- Added modular device support and devicetree bindings for ILI9341, ILI9488, CST816S, XPT2046, and GPIO button input, updating several board configurations for display/touch/backlight/keyboard/battery. - Added a setting to control deprecated HAL usage (device property + Kconfig).

+  M5Stack Cardputer Adv keyboard, a TCA8418 I2C keypad-scan IC wired as a 7x8 matrix behind
+  a 4x14 key grid identical to the base Cardputer's. Exposes a KEYBOARD_TYPE device.
+  Sym (fn) and shift are consumed internally and never emitted as their own key events;
+  sym+shift together toggles caps lock. Regular keys emit their lowercase/uppercase/sym-layer
+  ASCII character or LVGL navigation key depending on which layer is active.

+  M5Stack Cardputer internal GPIO matrix keyboard: 4 rows x 14 columns, scanned via 3
+  binary-encoded column-select output pins and 7 row input pins. Exposes a KEYBOARD_TYPE
+  device. Modifier keys (fn/shift/ctrl/opt/alt/tab) are consumed internally and never emitted
+  as their own key events. Regular keys emit their ASCII character (shifted variant when
+  shift or ctrl is held). With fn held: del -> forward delete, enter -> enter, ` -> escape,
+  , -> left, / -> right, ; -> previous (group navigation), . -> next (group navigation).
