[FROM-ML] platform/x86: msi-wmi-platform: Add PL1/PL2 support via firmware attributes

Adds PL1, and PL2 support through the firmware attributes interface.
The min and max values are quirked, and the attributes are only defined
if they are set to a non-zero value. These values are meant to be set
in conjunction with shift mode, where shift mode automatically sets
an upper bound on PL1/PL2 (e.g., low-power would be used with 8W).
