ACPI: platform_profile: Add concept of a "custom" profile 



When two profile handlers don't agree on the current profile it's ambiguous
what to show to the legacy sysfs interface.

Add a "custom" profile string that userspace will be able to use the legacy
sysfs interface to distinguish this situation..

Additionally drivers can choose to use this to indicate that a user has
modified driver settings in a way that the platform profile advertised by
a driver is not accurate.
