[PATCH v6 19/22] drm/rockchip: dw_hdmi_qp: Mask HPD IRQ in rk3576_io_init()

[Cristian Ciocaltea <cristian.ciocaltea@collabora.com>]

Mask the RK3576 HPD interrupt in io_init() so it starts disabled,
matching the RK3588 behavior.  This prevents spurious interrupts before
the bridge framework enables HPD via the .hpd_enable() callback.
