drm/i915: Fix the VDSC_PW2 power domain enum value
The POWER_DOMAIN_TRANSCODER() macro depends on the
POWER_DOMAIN_TRANSCODER_A/B .. DSI_A/C enum values to be consecutive,
move POWER_DOMAIN_TRANSCODER_VDSC_PW2 after these to ensure this. The
wrong order didn't cause a problem, since the DSI_A/C domains are in
always-on power wells on all relevant platforms. The same power well
ends up being enabled/disabled when the VDSC_PW2 domain is selected
incorrectly.
While at it add a code comment about enum values that need to stay
consecutive.
