A dummy read of APCI3120_TIMER_MODE_REG resets the analog input FIFO. Introduce
a helper function to clarify this.
It's not necessary to do a dummy read of the FIFO (base + 0) before reseting it.
Remove the unnecessary dummy reads.
The APCI3120_TIMER_MODE_REG is a 16-bit register. This fixes a couple 8-bit reads.
