TCH tap: extend DL sniffing feature to support CSD modes
Our debug feature for TCH DL sniffing reads the content of the DSP's
a_dd_0 buffer (or a_dd_1 for TCH/H subchannel 1) at appropriate times
and forwards captured bits to the host. This feature was originally
implemented for TCH/FS, TCH/EFS and TCH/HS - now extend it to cover
TCH/F data modes too.
