Subject: ACPI: property: Fix type detection of unified integer reading
 functions
Patch-mainline: v6.0-rc3
Git-commit: 06865077b34c792181e3c4f82417a2888c6e7453
References: jsc#PED-1408

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.

Fixes: 923044133367 ("ACPI: property: Unify integer value reading functions")
