[RESEND PATCH 6/7] drm/dp: Add a helper to get the SDP type as a string

[Ankit Nautiyal <ankit.k.nautiyal@intel.com>]

Introduce dp_sdp_type_get_name() to get the SDP type as a string.
Use this to log the SDP type based on the sdp_type fields of the
VSC and AS SDPs instead of the hardcoded strings.

While at it, rename "SDP : AS_SDP" to "SDP : Adaptive Sync"
