This adds the above APIs to the v4l2 core. This is based on version v1.2
of the RFC titled "V4L - Support for video timings at the input/output interface"
Following new ioctls are added:-

        - VIDIOC_ENUM_DV_PRESETS
        - VIDIOC_S_DV_PRESET
        - VIDIOC_G_DV_PRESET
        - VIDIOC_QUERY_DV_PRESET
        - VIDIOC_S_DV_TIMINGS
        - VIDIOC_G_DV_TIMINGS

Please refer to the RFC for the details. This code was tested using vpfe
capture driver on TI's DM365. Following is the test configuration used :-

Blu-Ray HD DVD source -> TVP7002 -> DM365 (VPFE) ->DDR

A draft version of the TVP7002 driver (currently being reviewed in the mailing
list) was used that supports V4L2_DV_1080I60 & V4L2_DV_720P60 presets.

A loopback video capture application was used for testing these APIs. This calls
following IOCTLS :-

 -  verify the new v4l2_input capabilities flag added
 -  Enumerate available presets using VIDIOC_ENUM_DV_PRESETS
 -  Set one of the supported preset using VIDIOC_S_DV_PRESET
 -  Get current preset using VIDIOC_G_DV_PRESET
 -  Detect current preset using VIDIOC_QUERY_DV_PRESET
 -  Using stub functions in tvp7002, verify VIDIOC_S_DV_TIMINGS
    and VIDIOC_G_DV_TIMINGS ioctls are received at the sub device.
 -  Tested on 64bit platform by Hans Verkuil

The video_device::minor field is used where it shouldn't, either to

- test for error conditions that can't happen anymore with the current
  v4l-dvb core,
- store the value in a driver private field that isn't used anymore,
- check the video device type where video_device::vfl_type should be
  used, or
- create the name of a kernel thread that should get a stable name.

Remove or fix those use cases.

Report output values as 1/1000 of earth gravity.

Output values from lis3 can be read from sysfs position entry and from
input device.  Input device can be accessed as event device and as
joystick device.  Joystick device can be in two modes.  Meaning of the
output values varies from case to case depending on the chip type and
configuration (scale).  Only joystick interface in JS_CORR_BROKEN mode
returned somehow similar output values in different configurations.
Joystick device is in that state by default in case of lis3.

Position sysfs entry, input event device and raw joystick device have been
little bit broken since meaning of the output values has been varied
between 12 and 8 bit devices.  Applications which relayed on those methods
failed if the chip is different than the expected one.

This patch converts output values to mean similar thing in different
configurations.  Both 8 and 12 bit devices reports now same acceleration
values.  If somebody implements full scale support to the driver, output
values will still mean the same.  Scaling factor and input device range
must be updated in that case.

Joystick interface in JS_CORR_BROKEN mode is not touched by this patch.
All other interfaces have different scale after this change.  For 12 bit
device scaling factor is 0.977 which keeps scaled and unscaled values are
quite close to each others.  For 8 bit device, scaled values are 18 times
bigger than unscaled values.
