Since all read/write operations are in TDM are channel based, polling on TDM channel
for data instead of TDM port before going for read/write.
Also corrected a faulty error leg.

TDM Framework is an attempt to provide a platform independent layer which can offer a standard interface for TDM access to different client modules.
Beneath, the framework layer can house different types of TDM drivers to handle various TDM devices, the hardware intricacies of the devices being completely taken care by TDM drivers.
This framework layer will allow any type of TDM device to hook with it.
For example Freescale controller as on MPC8315, UCC based TDM controller, etc
The main functions of this Framework are:
- provides interface to TDM clients to access TDM functionalities.
- provides standard interface for TDM drivers to hook with the framework.
- handles various data handling stuff and buffer management.
In future this Framework will be extended to provide Interface for Line control devices also. For example SLIC, E1/T1 Framers etc.
Presently the framework supports only Single Port channelised mode.
Also the configurability options are limited which will be extended later on.
Only kernel mode TDM clients are supported currently. Support for User mode clients will be added later.
