Set a sub-device's owner field to the caller's module, provided as an
argument to the function. v4l2_device_register_subdev() becomes a macro
passing THIS_MODULE to the __v4l2_device_register_subdev() function.

In commit 8caab75fd2c2 ("spi: Generalize SPI "master" to "controller"")
some functions and struct members were renamed. To not break all drivers
compatibility macros were provided.
To be able to remove these compatibility macros push the renaming into
v4l2_spi_new_subdev().

As I2C and SPI parts of the V4L2 core got split, let's take
the chance and solve the CodingStyle issues there, as reported
by checkpatch --strict.

Currently, the i2c and spi subdev creation helpers
are calling BUG() when passed a NULL v4l2_device parameter.
This makes little sense; simply returning NULL seems more
sensible.
These two helpers may already return NULL on error, so callers
should already be checking for this, or at least be prepared
for a NULL result.

Introduce a new video4linux2 spi helper, to unregister a subdev.
This allows to get rid of some more ifdefs.

Separate the spi helpers to v4l2-spi.c, in order to get rid
of the ifdefery. No functional changes intended, this is
just a cosmetic change to organize the code better.
