The _noirq were previously chosen to make sure all the users of the
adapter were suspended by the time the adapter itself enters the
suspended state.
The {suspend,resume}_noirq usage was converted from an earlier
implementation based on suspend_late and resume_early:

I2C: Rework i2c-pxa suspend_late()/resume_early()
However, all the I2C devices are probed as children of its I2C adapter,
and hence the device model guarantees they get suspended before its
parent and resumed after it.
In other words, there's no need to use the _noirq hooks to get a
suspend/resume device/adapter order.
This commit changes this by using the suspend/resume PM hooks in the I2C
adapter.
