isci: Add Support for new TC completion codes

Update the SCI Core to comprehend the changes in the TC completion
codes from A0 to B0.  Specifically, there isnew R_ER code
differences for command and data FISes.

Changes are as follows:

1) 0x16 now additionally indicates an R_ERR received for a COMMAND
FIS being sent to a SATA target.  0x16 for SSP still indicates a
NAK received for a COMMAND frame.  Fix is to retry TC to be compliant
with SATA spec or ensure proper error handling of return value
(not spec compliant I don't believe).
2) 0x1B was previously called DONE_BREAK_RCVD for STP and
DONE_LL_ABORT_ERR for SSP.  Now it is universally called
DONE_LL_ABORT_ERR.  This is purely a superficial change.
3) 0x32 is no longer a reserved code.  Now it indicates
DONE_CMD_SDMA_ERR for STP/SSP.  There was a fatal error on the
SDMA for a command IU (includes Raw frames).  Consider retry,
but at a minimum gracefully fail the request.
4) 0x33 is no longer a reserved code.  Now it indicates
DONE_CMD_LL_ABORT_ERR for SSP.  There was a break receivd
during transmission of a command IU.  Consider retry, but
at a minimum gracefully fail the request.
