ACPI / ACPICA: Use helper function for computing GPE masks
In quite a few places ACPICA needs to compute a GPE enable mask with
only one bit, corresponding to a given GPE, set. Currently, that
computation is always open coded which leads to unnecessary code
duplication. Fix this by introducing a helper function for computing
one-bit GPE enable masks and using it where appropriate.
