6f4bb118a8 pm: policy: split policy APIs implementations
policy.c has grown organically, it contained many independent pieces of
code. This patch splits each logical unit into its own C file, making it
easier to browse the code.

1c2e988021 pm: device: De-couple device pm from system pm
PM_DEVICE is not attached to system managed device power management.
It is a very common use case targets with device runtime power
management that don't want system device power management enabled.

We introduce a new symbol (PM_DEVICE_SYSTEM_MANAGED) to explicit
control whether or not system device power management should be
globally enabled.

c5003e0eb1 pm: add device shell commands
Add support for a "pm" shell command to trigger suspend/resume as well
as runtime-get/put on devices. This is useful for testing during driver
development.

5a71eeb35c pm: policy: move constraints to policy API
The pm_constraint_* APIs were effectively used by the policy manager
only. This patch renames the API to the policy namespace and makes its
naming more explicit:

- pm_constraint_set -> pm_policy_state_lock_get()
- pm_constraint_release -> pm_policy_state_lock_put()
- pm_constraint_get -> pm_policy_state_lock_is_active()

The reason for these changes is that constraints can be of many types:
allow/disallow states, impose latency requirements, etc. The new naming
also makes explicit that the API calls will influence the PM policy
behavior.

All drivers and documentation have been updated accordingly.

Move policy code one level up for simplicity, since there is a single
source file. Source file has been renamed to "policy.c" to make things
clear.

Stats are an optional feature, moving it into a separate source file
improves code readability.
