ACPI: property: Fix type detection of unified integer reading functions

Browse Source 
The current code expects the type of the value to be an integer type,
instead the value passed to the macro is a pointer.
Ensure the size comparison uses the correct pointer type to choose the
max value, instead of using the integer type.
