drm/nv50: preserve an unknown SOR_MODECTRL value for DP encoders

This value interacts with some registers we don't currently know how to
program properly ourselves.  The default of 5 that we were using matches
what the VBIOS on early DP cards do, but later ones use 6, which would
cause nouveau to program an incorrect mode on these chips.
