[Intel-gfx] [PATCH 1/8] drm/i915/cdclk: s/-1/~0/ when dealing with unsigned values

From: Ville Syrjälä <ville.syrjala at linux.intel.com>
cdclk_pll_is_unknown() used ~0 when checking for the "VCO is
unknown" value, but the assignment uses -1. They are the same
in the end, but let's use the same ~0 form on both sides for
consistency.
