ITE: drivers/i2c/target: Remove hardware reset setting

Browse source 
In the interrupt pending routine, only the interrupt status needs to be
cleared at the end of the interrupt routine. There is no need to do a
hardware reset(HALT) to avoid clearing the next transfer interrupt when
the current transfer is completed.

Test: Testing this function does not cause I2C data/clk to get stuck on
the system platform.
