HID: Intel-thc-hid: Intel-thc: Introduce max input size control

This patch adds support for a new feature, named "Max Input Size
Control", allowing driver to set a maximum input size for RxDMA. This
enhancement aims to prevent RxDMA buffer overruns caused by data
corruption on the I2C bus, thereby improving overall system stability.

APIs added:
- thc_i2c_set_rx_max_size(): Set the maximum input size for I2C RxDMA.
- thc_i2c_rx_max_size_enable(): Enable or disable the max input size
  control.

As this max input size control feature is only applicable to RxDMA
and must remain disabled during SWDMA operations, it also involves
a change in SWDMA code to record the max input size control feature
state before SWDMA and restore the state after SWDMA.
