sdm: Update vendor HDR capability logic

HDR support capabilities were populated to SF, when panel and target
supports HDR. At SF, HDR layer is forced to GPU composition with new
HDR solution, if vendor does not support HDR. This change will populate
marking HDR support to true (for all display types) when primary panel
is internal.
