ACPI: platform_profile: Allow multiple handlers

Multiple drivers may attempt to register platform profile handlers,
but only one may be registered and the behavior is non-deterministic
for which one wins.  It's mostly controlled by probing order.

This can be problematic if one driver changes CPU settings and another
driver notifies the EC for changing fan curves.

Modify the ACPI platform profile handler to let multiple drivers
register platform profile handlers and abstract this detail from userspace.

To avoid undefined behaviors only offer profiles that are commonly
advertised across multiple handlers.

If any problems occur when changing profiles for any driver, then the
drivers that were already changed remain changed and the legacy sysfs
handler will report 'custom'.
