After commit 23287661af ("ipv6: Inhibit IPv4-mapped src address on the wire.")
Android failed to pass DatagramSocketTest#test_getRemoteSocketAddress:
fail: java.net.ConnectException: Address family not supported by protocol
Android side has patch "Fix DatagramSocketTest#test_getRemoteSocketAddress".
Unfortunately, which may not merge to Android 7.1 branch, so we have to fixes
it on kernel side.

It takes a bit of time to go through controller power up sequence and
initialization. To not stall the overall boot progress let's probe the
controller asynchronously, given that userspace is usually prepared for
hot-plugging of input devices and thus does not rely on particular
ordering.
Save about 0.35s on RK1808 EVB.

Currently, it's set active_sensor to NULL when stream off. But it
could be useful for ioctls (e.g. enum_frameintervals) to obtain
active sensor's infomations.
This patchs keep active_sensor always available and renew it
every time before starting stream in case media topology changed.
Meanwhile, get active_sensor info once async subdevice registered
completely.

Currently the maximum size of video is 4416x3312. For those sensors(5M
or 8M), it's not a good idea to scale up to max resolution by ISP.
This avoid video output resolution exceeding the isp sub-device
size.

userspace to subscribe. With these events, userspace could
init/de-init 3A tuning in proper time.
Only if isp sub-device input format is Raw Bayer and output
format is YUV, the 3A tuning is required.
