[Intel-gfx] [PATCH] drm/i915: Restore DMC required version for Skylake (1.26)

[Rodrigo Vivi]

With commit 4aa7fb9c ("drm/i915/dmc: Step away from symbolic
links") we started loading the firmware version directly
instead of symbolic links.

With this VERSION_REQUIRED variables changed the meaning
from minimal required to exact version required. Along
with this change we started using the latest stable
DMC firmware as the required one 1.26.

This patch is correct. However in some merge this
change got missed and it was overwritten by the old
version.

1.23 is unstable and can cause blank screens so let's
avoid it.
