[PATCH] drm/i915: Avoid enum conversion warning

[Nick Desaulniers]

Fixes the following enum conversion warning:

drivers/gpu/drm/i915/intel_ddi.c:1481:30: error: implicit conversion
from enumeration type 'enum port' to different enumeration type 'enum
intel_dpll_id' [-Werror,-Wenum-conversion]
        enum intel_dpll_id pll_id = port;
                           ~~~~~~   ^~~~
