[PATCH] I2C: Drop I2C_DEVNAME and i2c_clientname

I2C_DEVNAME and i2c_clientname were introduced in 2.5.68 [1] to help
media/video driver authors who wanted their code to be compatible with
both Linux 2.4 and 2.6. The cause of the incompatibility has gone since
[2], so I think we can get rid of them, as they tend to make the code
harder to read and longer to preprocess/compile for no more benefit.

I'd hope nobody seriously attempts to keep media/video driver compatible
across Linux trees anymore, BTW.
