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

/*

 * v4l2-i2c-drv.h - contains I2C handling code that's identical for

 *		    all V4L2 I2C drivers. Use this header if the

 *		    I2C driver is only used by drivers converted

 *		    to the bus-based I2C API.

/* 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.
