This change contains a generic cleanup of linux dependent parts of the dbg_gpu_gk20a.* files. The following changes have been made 1) Moving methods into ioctl_dbg.* inside common/linux/ 2) The structures dbg_session_gk20a and dbg_session_channel_data have been split into two parts. struct device *dev is removed from struct dbg_session_gk20a and instead packed into struct dbg_session_gk20a_linux alongwith dbg_session_gk20a and is moved into ioctl_dbg. dbg_session_gk20a is now rid of any linux dependencies and remains in dbg_gpu_gk20a. Similarly, struct file is removed from struct dbg_session_channel_data and is now packed into struct dbg_session_channel_data_linux alongwith dbg_session_channel_data and is moved into ioctl_dbg. struct dbg_session_channel_data is now rid of linux dependencies and remains in dbg_gpu_gk20a. 3) A callback function is added in order to release the dbg_session_channel_data.
