The threaded interrupt handler on RK3588 checks HPD IRQ status before deciding to continue with interrupt clearing and unmasking. However, this is not really necessary, since the hard interrupt handler already performs the very same verification before waking the handler thread.
Get rid of the redundant verification of the HPD interrupt status in the threaded interrupt handler.
