Define tracing macros for easy catpt debug. These cover all IPC message
types: requests, replies and notifications.

Signed-off-by: Cezary Rojewski <cezary.rojewski@intel.com>

Changes in v2:
- trace.h events for updating registers have been removed and usages
  replaced by dev_dbg (SRAMPGE/ LPCS)
- trace.h events for catpt_mbank and catpt_mregion have been removed
