To allow for easier debug of failing commands we
have added a capability to print TRB and command
packet when we start execution of the TRB(on
DEBUG_VERBOSE level) and when the TRB failed to
execute correctly(on DEBUG_ERROR level). Additionally
we will also print error interrupt status and interrupt
status register on failed SD command.
