drm/amd/display: Ensure HPD source index is valid for dcn20/dcn201 link encoders

Browse source

This patch adds a boundary check for the hpd_source index during the
link encoder creation process for dcn20/dcn201 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.
