On pseries machines the detection for max_bus_speed should be done
through an OpenFirmware property. This patch adds a function to perform this
detection and a hook to perform dynamic adding of the function only for
pseries.

I assume that on x86 machines, the
max_bus_speed property will be properly set already.

The refactor is done because the function that was used by drm is more
architecture goo than module-specific. Whilst the function also needed a
platform-specific implementation to get PCIE Gen2 speeds on ppc64.
