This patch provides a option for users to enable multi-channel function support
in Blackfin ASoC driver. Because Blackfin is without MMU, it is easy for us and
the user to enable this function at compiling stage not dynamically on the fly.

- Setting the TFS pin selector for SPORT 0 based on whether the selected
  port id F or G. If the port is F then no conflict should exist for the
  TFS. When Port G is selected and EMAC then there is a conflict between
  the PHY interrupt line and TFS.  Current settings prevent the conflict
  by ignoring the TFS pin when Port G is selected. This allows both
  ssm2602 using Port G and EMAC concurrently.

 - some code cleanup

With MMAP enabled (DMA mode) on the AD1981, there is +/- 250ms of delay between
writing data to alsa and audio starts coming out of the AD1981.

Copy more data to local buffer before starting DMA
