Subject: [PATCH] drm/i915: Fix PCH names for KBP and CNP.
Git-commit: 23247d715d3cf679cac24d1c4de2d76774a2a495
Patch-mainline: v4.14-rc1
References: FATE#322643 bsc#1055900

No functional change.

KBP was based on SPT and spec wasn't clear about the full name.
There was the initial point of the "Point" confusion.

Later the split with Coffee Lake and Cannon Lake both using CNP
and also some uncertainty from the specs we had at that time
made us to propagated the mistake along.

So, let's fix this now and avoid propagating these wrong
"points".
