There haven't been any I2C driver that use the legacy suspend/resume

remove support for legacy suspend/resume for I2C drivers.
Since there aren't any special bus specific things to do during
suspend/resume and since the PM core will automatically fallback directly to
using the device's PM ops if no bus PM ops are specified there is no need to
have any I2C bus PM ops.

I'll keep this for 3.20, 3.19 is too close now. But thanks, the diffstat
looks great :) Just curious, has buildbot tested this already?
No, but I did allyesconfig on both ARM and x86. As well as a `grep "
i2c_driver " -A20 * -r | grep '\(suspend\|resume\)'` and running the
following cocci script.
@@
identifier fn;
identifier drv;
@@
struct i2c_driver drv = {
...,
* .suspend = fn,
...,
};
@@

None of those methods found anything, so I'm quite confident that there are
no users left.
