If the camera was set to output formats like RGB565 YUYV or SBGGR10,
the resulting image was scrambled due to erroneous interpretations of
horizontal parameter's units.

This patch in fourcc_to_ipu_pix, eliminate also the pixel formats mappings
that, first are not used within mainline code and second, standing at
the datasheets, they will not work properly:

The IPU internal bus support only the following data formatting

 1 YUV 4:4:4 or RGB-8 bits per color component
 2 YUV 4:4:4 or RGB-10 bits per color component
 3 Generic data (from sensor to the system memory only)

And format conversions are done:
 - from memory: unpacking from other formats to IPU supported ones
 - to memory: packing in the inverse order.

So, assigning a packing/unpacking strategy to the IPU for those formats
will produce a packing to memory and not the inverse.

[media] v4l: removal of old, obsolete ioctls

type of R/W arguments. They were fixed, but the old ioctl names are
still there, maintained to avoid breaking binary compatibility:

There's no sense on preserving those forever, as it is very doubtful

Removing them will allow us to remove some magic done at the V4L ioctl

A static var is evil, especially if a device has two boards with

its config during setup.

[media] tuner-core: Better implement standby mode

In the past, T_STANDBY were used on devices with a separate radio tuner to
mark a tuner that were disabled. With the time, it got newer meanings.

Also, due to a bug at the logic, the driver might incorrectly return
T_STANDBY to userspace.

So, instead of keeping the abuse, just use a boolean for storing
such information.

We can't remove T_STANDBY yet, as this is used on two other drivers. A
latter patch will address its usage outside tuner-core.
