i2c: Move i2c-dev interfaces to i2c-dev.h
Move the i2c-dev support into <linux/i2c-dev.h> where it should always have lived. Now <linux/i2c.h> no longer holds stuff related to the optional userspace /dev/i2c-X interface. Improve the descriptions for these ioctl requests. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Jean Delvare <khali@linux-fr.org>
