media: tw686x: Register the irq at the end of probe
We got the following warning when booting the kernel:
[ 3.243674] INFO: trying to register non-static key.
[ 3.243922] The code is fine but needs lockdep annotation, or maybe
[ 3.244230] you didn't initialize this object before use?
[ 3.245642] Call Trace:
[ 3.247836] lock_acquire+0xff/0x2d0
[ 3.248727] tw686x_audio_irq+0x1a5/0xcc0 [tw686x]
[ 3.249211] tw686x_irq+0x1f9/0x480 [tw686x]
The lock 'vc->qlock' will be initialized in tw686x_video_init(), but the
driver registers the irq before calling the tw686x_video_init(), and we
got the warning.
Fix this by registering the irq at the end of probe
