HID: hid-goodix: Add Goodix HID-over-SPI driver
This patch introduces a new driver to support the Goodix GT7986U
touch controller. This device is not compatible with Microsoft's
HID-over-SPI protocol and therefore needs to implement its own
flavor. The data reported is packaged according to the HID
protocol but uses SPI for communication to improve speed. This
enables the device to transmit not only coordinate data but also
corresponding raw data that can be accessed by user-space programs
through the hidraw interface. The raw data can be utilized for
functions like palm rejection, thereby improving the touch experience.
Key features:
- Device connection confirmation and initialization
- IRQ-based event reporting to the input subsystem
- Support for HIDRAW operations (GET_REPORT and SET_REPORT)
