[PATCH] tree-wide: correct the spelling Ghz -> GHz

[PATCH] tree-wide: correct the spelling Ghz -> GHz

[Ronan Pigott]

This mispelling was present in the configuration, so I retained parsing
of the legacy BandModifier*Ghz options for compatibility. Without this
change anyone spelling GHz correctly in their configs would be very
confused.
