TX Sample Counter

The audio sample number of sending into TXFIFO. When one sample is
put into TXFIFO by DMA or by host IO, the TX sample counter register
increases by one. The TX sample counter register can be set to any
initial value at any time. After been updated by the initial value, the
counter register should counter on base of this initial value.
