drm/edid: extract base section header processing into helper

Browse source

Extract the DisplayID base section header logging and non_desktop
detection from update_displayid_info() into a dedicated helper,
drm_displayid_process_base_section_header(). Remove the break so the
iterator walks through all data blocks, preparing for future patches
that will parse additional block types within the loop.

The helper is called only once for the base section via a
base_section_header_processed flag. Since version and primary_use are
only captured from the base section, and extension sections carry a
primary use of zero per spec, the non_desktop logic is unaffected.

No functional change.
