[PATCH v4 1/2] drm/i915/cnl; Add macro to get PORT_TX register

Wed Mar 14 06:14:11 UTC 2018
This patch creates a new macro to get PORT_TX register for any given DW.
This removes the need of defining register address for each port & DW.
Changes since V1:
- Use underscope prefix, as macro isn't returning an mmio reg(Lucas)
- Merge patch 1 & 2 of the series
Changes since V2:
- remove _MMIO_PORT6_LN macro (Rodrigo)
