drm/exynos: exynos_hdmi: Pass correct pointer to free_irq()

free_irq() expects the same pointer that was passed to request_threaded_irq(),
otherwise the IRQ is not freed.

The issue was found using the following coccinelle script:

<smpl>
@r1@
type T;
T devid;
@@
request_threaded_irq(..., devid)

@r2@
type r1.T;
T devid;
position p;
@@
free_irq@p(..., devid)

@@
position p != r2.p;
@@
*free_irq@p(...)
</smpl>
