PM: core: Add two macros for walking device links
Add separate macros for walking links to suppliers and consumers of a
device to help device links users to avoid exposing the internals of
struct dev_links_info in their code and possible coding mistakes related
to that.
Accordingly, use the new macros to replace open-coded device links list
walks in the core power management code.
No intentional functional impact.
