Implement .enable_hpd() and .disable_hpd() phy ops for RK3576 and RK3588 SoCs, used by the corresponding bridge callbacks for HPD activation control.
Consolidate the interrupt clear-and-unmask sequence into enable_hpd() and the mask-only operation into disable_hpd(), replacing the open-coded register writes in the interrupt handlers and io_init(). The .setup_hpd() phy op, which was previously called from dw_hdmi_qp_init_hw(), is no longer needed and its users are removed.
