CNL macros for register groups CNL_PORT_TX_DW2_* / CNL_PORT_TX_DW5_* are
configured incorrectly wrt definition of _CNL_PORT_TX_DW_GRP.
v2: Jani suggested to keep the macros organized semantically i.e., by
function, secondarily by port/pipe/transcoder.->(dw, port)

There are still inconsistencies in some macro definitions. The macros
for MG phy registers are (port, ln) e.g.,
MG_TX2_LINK_PARAMS(port, ln) and also CNL_PORT_TX_DW4_LN(port, ln)
whereas for ICL -> _ICL_PORT_PCS_DW_LN(dw, ln, port).
Do you feel that we need to make these definitions consistent and what
should be the sequence -> (dw, ln, port)/(ln, port) or (dw, port, ln)/
(port,ln)?
