[Intel-gfx] [PATCH 2/6] drm/i915/sdvo: Use named initializers for the SDVO command names

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Use named initializers to make it easier to associate the SDVO debug
prints with the SDVO command defines. Also switch to using ARRAY_SIZE()
instead of assuming that SDVO_CMD_STATUS_SCALING_NOT_SUPP is the last
command type.
