Since USB receives STATUS_RSSI updates through the interrupt endpoint,
there is no need to poll with USB, so get rid of the polling.
Note this also changes the order in which the probing of USB devices is done,
to avoid si470x_set_chan getting called before the interrupt endpoint is being
monitored.

Reading registers from the pcear USB dongles with the si470x causes a
loud pop (and an alsa buffer overrun). Since most radio apps periodically
call G_TUNER to update mono/stereo, signal and afc status this leads
to the music . pop . music . pop . music -> not good.
On the internet there is an howto for flashing the pcear with a newer
firmware from the silabs reference boardto fix this, but:
1) This howto relies on a special version of the driver which allows
firmware flashing
2) We should try to avoid the answer to a bug report being upgrade your
firmware, if at all possible
3) Windows does not suffer from the pop sounds
After a quick look at the driver I found at that the register reads are
not necessary at all, as the device gives us the necessary status through
usb interrupt packets, and the driver already uses these!

Some devices which use the tea575x tuner chip don't allow bit banging the
lines, instead they offer a method to directly set / get the contents of the
25 bit shift-register in the chip. Notably the Griffin radioSHARK USB radio
receiver does this.

Fixes an omission in the new v4l2_ioctls table: VIDIOC_TRY_EXT_CTRLS
must get the INFO_FL_CTRL flag, just like all the other control
related ioctls, otherwise the ioctl core won't know it also has
to check whether v4l2_fh->ctrl_handler is non-zero before it can
decide that this ioctl is not implemented.
Caught by v4l2-compliance while I was testing the mem2mem_testdev driver.

commit 5126f2590b
"v4l2-dev: add flag to have the core lock all file operations"
introduced an additional bit flag (V4L2_FL_LOCK_ALL_FOPS) that
should be set by drivers that use the v4l2 core lock for all file
operations. Since this driver has been merged at the same time as
the core changes it doesn't set this flags and thus its all file
operations except IOCTL are not properly serialized. Fix this by
adding file ops locking in the driver.

The API reference documents that the KEEP_CONFIG flag tells the

documentation (dev-subdev.xml) prohibited any changes to the rest of the
pipeline. Resolve the conflict by changing the API reference to disallow
changes.
