V4L/DVB: v4l: remove obsolete include/media/v4l2-i2c-drv.h file

Browse Source 
The include/media/v4l2-i2c-drv.h header was used to be able to compile drivers
in the v4l-dvb hg repository for legacy kernels (mainly pre-2.6.26) without
creating an #ifdef mess.

The hg repository dropped support for kernels < 2.6.26 so we can remove this
header. All i2c drivers that used it have now been converted to use proper
i2c code. The header was a hack, but it did its job well. So I would call
this an honorable removal. :-)

/* NOTE: the full version of this header is in the v4l-dvb repository
* and allows v4l i2c drivers to be compiled on pre-2.6.26 kernels.
* The version of this header as it appears in the kernel is a stripped
* version (without all the backwards compatibility stuff) and so it
* looks a bit odd.
*
* If you look at the full version then you will understand the reason
* for introducing this header since you really don't want to have all
* the tricky backwards compatibility code in each and every i2c driver.
*
* If the i2c driver will never be compiled for pre-2.6.26 kernels, then
* DO NOT USE this header! Just write it as a regular i2c driver.
