[PATCH -next] drm/i915: Remove set but not used variable 'intel_dig_port'

[YueHaibing]

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/gpu/drm/i915/display/intel_ddi.c: In function 'intel_ddi_get_config':
drivers/gpu/drm/i915/display/intel_ddi.c:3774:29: warning:
 variable 'intel_dig_port' set but not used [-Wunused-but-set-variable]
  struct intel_digital_port *intel_dig_port;

It is never used, so can be removed.
