platform/x86: acer-wmi: use an ACPI bitmap to set the platform profile choices

Browse Source 
Currently the choices for the platform profile are hardcoded. There is
an ACPI bitmap accessible via WMI that specifies the supported profiles,
use this bitmap to dynamically set the choices for the platform profile.
