SKUs that lacks on the full port F split will just time out
when touching this power well bits, causing a noisy warn.
This macro style is a deviation from the original definition in use
for other platforms, but it at least avoid code duplication.
Other smart alternatives like providing a joint list was also considered
but it would require some extra memory handling that would be
a deviation from the original simplistic definitions here anyways,
plus requiring extra tests and possibly creating some corner cases
for one single platform. So let's move with the simplest and safest
approach.
