💖 DESCRIPTION 💖

okay so here's the vibe: this function handles the HPD IRQ state transitions from LOW to HIGH 👑 — and yes that includes the cases when there are back to back HPD IRQ HIGH, no cap, it handles those too.

and what does that mean?? it means the start of a new link training request 🔥 or a sink status update 💫 that's the whole thing. those transitions are the signal, and this function is the main character that deals with them.
