Subject: drm/i915/cnl: Fix CNL macros for Voltage Swing programming
Git-commit: 3b91a93597327f682a1c4392350ced99a44840b7
Patch-mainline: v5.0-rc7
References: bsc#1113956
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)
Fixes: 4e53840fdfdd ("drm/i915/icl: Introduce new macros to get combophy registers")
