drm/amd/display: Add hpd_source index check for DCE60/80/100/110/112/120 link encoders

Browse source

This patch adds a boundary check for the hpd_source index during the
link encoder creation process for all DCExxx IP's. The check ensures
that the index is within the valid range of the link_enc_hpd_regs array
to prevent out-of-bounds access.
