V4L/DVB (7276): soc-camera: deactivate cameras when not used

Only attach cameras to the host interface for probing, then detach until
open. This allows platforms with several cameras on an interface,
physically supporting only one camera, to handle multiple cameras and
activate them selectively after initial probing. The first attach during
probe is needed to activate the host interface to be able to physically
communicate with cameras.

The IDR structures are protected by holding namepspace_sem for write

IDs are allocated when a previously unshared vfsmount becomes the
first member of a peer group.  When a new member is added to an
existing group, the ID is copied from one of the old members.

IDs are freed when the last member of a peer group is unshared.

Setting the MNT_SHARED flag on members of a subtree is done as a
separate step, after all the IDs have been allocated.  This way an
