[PATCH v2 1/4] platform/x86: ISST: Use fuse enabled mask instead of allowed levels

[Srinivas Pandruvada]

Allowed level mask is a mask of levels, which are currently allowed to
dynamically switch by the OS. Fused mask is a mask of all levels even if
OS is not allowed to switch.

Even if OS is not allowed to dynamically switch, it is still possible for
user to boot to a level by using BIOS option. To decide which level to
boot next time, user wants to check parameters (power, performance or
thermal) of that level to decide.

So, when passing the level mask for display to user space, use fuse
enabled mask, which has all levels.
