drm/i915/bxt: Reversed polarity of PORT_PLL_REF_SEL bit

For BXT, description of polarities of PORT_PLL_REF_SEL
has been reversed for newer Gen9LP steppings according to the
recent update in Bspec. This bit now should be set for
"Non-SSC" mode for all Gen9LP starting from B0 stepping.

v2: Only B0 and newer stepping should be affected by this
change.
