[DM/Input] Add ADC joystick, keyboard, and touchscreen drivers (#11679)

* [DM/Input] Add ADC joystick, keyboard, and touchscreen drivers

Add polling input drivers for ADC-connected joysticks and resistor-
ladder keys. Parse Linux-compatible device-tree bindings, acquire ADC
channels through the IIO framework, and report absolute-axis and key
events.

Add an SPI touchscreen driver for ADS7843, ADS7845, ADS7846, ADS7873,
TSC2046, and XPT2046-compatible controllers. Support pen interrupts,
coordinate and pressure reporting, sample filtering, regulator control,
power management, and common touchscreen properties.

Add an I2C touchscreen driver for Goodix GT9xx controllers with
multi-touch reporting, GPIO-based reset and address selection, interrupt
handling with polling fallback, regulator control, panel configuration,
and alternate-address recovery.

Adapt the drivers to the RT-Thread device model and input framework,
following the corresponding Linux input drivers and device-tree
bindings.
