HID: Intel-thc-hid: Intel-quicki2c: Refine recover callback
Refine recover flow:
1. Use workqueue to handle recover flow instead of processing in irq
handler.
2. Call thc_rxdma_reset() API to simplify the recover operation.
3. Disable interrupt during whole recover flow.
4. If recover fails, disable interrupt to avoid interrupt storm.

HID: Intel-thc-hid: Intel-quicki2c: Add output report support
Add support for HID output reports in the intel-quicki2c driver by
implementing the output_report callback in the HID low-level driver
interface.
This enables proper communication with HID devices that require
output report functionality, such as setting device configuration or
updating device firmware.

HID: Intel-thc-hid: Intel-quicki2c: Support writing output report format
There are two output formats requested in the HID-over-I2C specification:
- Command format (set feature/set report): encoded command written to
command register, followed by data written to data register
- Output report format: all data written directly to output register
Current quicki2c_init_write_buf() implementation only supports the
command format.
Extend quicki2c_init_write_buf() to automatically detect the output
format based on the presence of command parameters and prepare the
appropriate output buffer accordingly.

Replace memcpy operations with put_unaligned_le16() when writing 16-bit

This change improves code clarity and ensures proper handling of unaligned
memory access.

HID: intel-thc-hid: Intel-quicki2c: Enhance driver re-install flow
After driver module is removed and during re-install stage, if there
is continueous user touching on the screen, it is a risk impacting
THC hardware initialization which causes driver installation failure.
This patch enhances this flow by quiescing the external touch
interrupt after driver is removed which keeps THC hardware
ignore external interrupt during this remove and re-install stage.
