Subject: [PATCH] drm/i915: Fix DPLCLKA_CFGCR0 bits for Port F.
Git-commit: 376faf8a3b2ff497b1f1583ab4b23bc650711764
Patch-mainline: v4.17-rc1
References: FATE#322643 bsc#1055900
Since when it got introduced with commit '555e38d27317
("drm/i915/cnl: DDI - PLL mapping")' the support for Port F
was wrong, because Port F bits are far from bits used
for A to E.
Since Port F is not used so far we don't need to propagate
Fixes back there.
V2: Reuse _SHIFT definition to avoid complicated duplication (DK).
