Subject: i2c: core: Convert to dev_pm_domain_attach|detach()

Previously only the ACPI PM domain was supported by the i2c bus.

Let's convert to the common attach/detach functions for PM domains,
which currently means we are extending the support to include the
generic PM domain as well.

Subject: PM / Domains: Move dev_pm_domain_attach|detach() to pm_domain.h

The commit 46420dd73b80 (PM / Domains: Add APIs to attach/detach a PM
domain for a device) started using errno values in pm.h header file.
It also failed to include the header for these, thus it caused
compiler errors.

Instead of including the errno header to pm.h, let's move the functions
to pm_domain.h, since it's a better match.
