[media] v4l2: add new VIDIOC_DBG_G_CHIP_NAME ioctl
Simplify the debugging ioctls by creating the VIDIOC_DBG_G_CHIP_NAME ioctl.
This will eventually replace VIDIOC_DBG_G_CHIP_IDENT. Chip matching is done
by the name or index of subdevices or an index to a bridge chip. Most of this
can all be done automatically, so most drivers just need to provide get/set
register ops.
In particular, it is now possible to get/set subdev registers without
requiring assistance of the bridge driver.

to be updated for a PAL/NTSC capture card.
- Setup the correct initial std based on the TV tuner type.
- Remember the exact std the user selected, don't map it to STD_PAL or NTSC.
- Use v4l2_disable_ioctl to disable ioctls based on the board config and
drop a lot of checking code in each of those ioctls since that is no longer
needed.
- enum_input should use tvnorms to fill its std field.
- configure the input, std and initial tuner frequency at driver initialization.
- fix std handling in the s2250 driver.
- the code handling scaling for devices without a scaler was broken. This is
now fixed.

[media] v4l2-ctrls: eliminate lockdep false alarms for struct v4l2_ctrl_handler.lock
When calling v4l2_ctrl_add_handler(), lockdep would detect a potential
recursive locking problem on a situation that is by design intended and
not a recursive lock. This happened because all struct
v4l2_ctrl_handler.lock mutexes were created as members of the same lock
class in v4l2_ctrl_handler_init(), and v4l2_ctrl_add_handler() takes the
hdl->lock on two different v4l2_ctrl_handler instances.
This change breaks the large lockdep lock class for struct
v4l2_ctrl_handler.lock and breaks it into v4l2_ctrl_handler
instantiation specific lock classes with meaningful class names.
This will validly eliminate lockdep alarms for v4l2_ctrl_handler locking
validation, as long as the relationships between drivers adding v4l2
controls to their own handler from other v4l2 drivers' control handlers
remains straightforward.
struct v4l2_ctrl_handler.lock lock classes are created with names such
that the output of cat /proc/lockdep indicates where in the v4l2 driver
code v4l2_ctrl_handle_init() is being called on instantiations:
ffffffffa045f490 FD: 10 BD: 8 +.+...: cx2341x:1534:(hdl)->lock
