Ville Syrjälä ed5fa90660 drm/i915: Do not create a new max_bpc prop for MST connectors 
We're not allowed to create new properties after device registration
so for MST connectors we need to either create the max_bpc property
earlier, or we reuse one we already have. Let's do the latter apporach
since the corresponding SST connector already has the prop and its
min/max are correct also for the MST connector.

The problem was highlighted by commit 4f5368b554 ("drm/kms:
Catch mode_object lifetime errors") which results in the following
spew:
[ 1330.878941] WARNING: CPU: 2 PID: 1554 at drivers/gpu/drm/drm_mode_object.c:45 __drm_mode_object_add+0xa0/0xb0 [drm]
