i2c: Add driver suspend/resume/shutdown support
Driver model updates for the I2C core: - Add new suspend(), resume(), and shutdown() methods. Use them in the standard driver model style; document them. - Minor doc updates to highlight zero-initialized fields in drivers, and the driver model accessors for "clientdata". If any i2c drivers were previously using the old suspend/resume calls in "struct driver", they were getting warning messages ... and will now no longer work. Other than that, this patch changes no behaviors; and it lets I2C drivers use conventional PM and shutdown support.
