[PATCH] PM / Domains: Move dev_pm_domain_attach|detach() to pm_domain.h

[Ulf Hansson <ulf.hansson@linaro.org>]

The commit below, started using errno values in pm.h header file. It
also failed to include the header for these, thus it caused compiler
errors.

46420dd73b800f87a19af13af5883855cf38cb08
(PM / Domains: Add APIs to attach/detach a PM domain for a device)

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