power: supply: core: introduce dev_to_psy()
The psy core and drivers currently use dev_get_drvdata() to go from a
'struct device' to its 'struct power_supply'.
This is not typesafe and or documented.
Introduce a new helper to make this pattern explicit.
Instead of using dev_get_drvdata(), use container_of_const() which
also preserves the constness.
Furthermore 'dev' does need to be dereferenced anymore and at some point
the drvdata could be reused for something else.
