Brian King f1dd153121 powerpc/pseries: Make 32-bit MSI quirk work on systems lacking firmware support 
Recent commit e61133dda4 added support
for a new firmware feature to force an adapter to use 32 bit MSIs.
However, this firmware is not available for all systems. The hack below
allows devices needing 32 bit MSIs to work on these systems as well.
It is careful to only enable this on Gen2 slots, which should limit
this to configurations where this hack is needed and tested to work.

[Small change to factor out the hack into a separate function -- BenH]
