HID: intel-thc-hid: intel-thc: Add THC PIO operation APIs
THC PIO (programmed I/O) operations are very similar with general
SPI/I2C read/write operation to access external slave device on the bus
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
