HID: Intel-thc-hid: Intel-thc: Introduce interrupt delay control

This patch adds support for a new feature, named "Interrupt Delay",
allowing driver to set a specific delay time for next interrupt
detection. It gives driver a capability to control THC waiting time for
the next interrupt, to reduce the likelihood of spurious readings.

APIs added:
- thc_i2c_set_rx_int_delay(): Set I2C Rx input interrupt delay value
- thc_i2c_rx_int_delay_enable(): Enable or disable I2C Rx interrupt delay

As this interrupt delay 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.

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.

THC PIO (programmed I/O) operations are very similar with general

through internal FIFO.

THC PIO operations are split into 4 steps:
1. prepare: configure hardware with correct opcode, slave address, and
fill the PIO FIFO
2. start: set start bit to issue a bus send/receive
3. wait: wait for bus sending/receiving completion
4. complete: check send/receive data in FIFO and return
