it83xx/i2cs: add i2c slave function
The I2C function of IT8320 is used as the slave.
The slave channel A can support 16-byte FIFO for
read and write data. The enhanced I2C channel D,
E and F can support read and write 256-byte data
by DMA mode.
When master transmits data to slave, the interrupt
signal will generate, and the data will be saved
to buffer.
