device: introduce and use dev_get_domain_id
To avoid having constructs like 'dev->path.domain.domain' in the SoC
code, create the 'dev_get_domain_id' helper function that returns the
domain ID of either that device if it's a domain device or the
corresponding domain device's domain ID, and use it in the code.
If this function is called with a device other than PCI or domain type,
it won't have a domain number. In order to not need to call 'die',
'dev_get_domain_id' will print an error and return 0 which is a valid
domain number. In that case, the calling code should be fixed.
