media: tw686x: Register the irq at the end of probe



[ Upstream commit fb730334e0f759d00f72168fbc555e5a95e35210 ]

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
