Subject: [PATCH v2 2/3] platform/x86: acer-wmi: use an ACPI bitmap to set
 the platform profile choices

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.
