[PATCH v3 13/22] ACPI: platform_profile: Require handlers to support balanced profile

[Mario Limonciello]

As support for multiple simultaneous platform handers is introduced it's
important they have at least the balanced profile in common.

This will be used as a fallback in case setting the profile across one of the
handlers happens to fail.
