drm/amd/display: Add hpd_source index out-of-bounds check for dcn3x link encoder creation
This patch adds a boundary check for the hpd_source index during the
link encoder creation process for dcn3x 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.
