Contrary to popular belief, there is no such thing as a default IPA size on arm64. Anything goes, and implementations are the usual Wild West. The selftest infrastructure default to 40bit IPA, which obviously doesn't work for some systems out there. Turn VM_MODE_DEFAULT from a constant into a variable, and let guest_modes_append_default() populate it, depending on what the HW can do. In order to preserve the current behaviour, we still pick 40bits IPA as the default if it is available, and the largest supported IPA space otherwise.
