[SERIAL] Fix serial8250 driver initialisation ordering
Commit 7493a314cb83797ce612a577475aacaedc553fed changed the ordering
of the registration of the platform device driver vs the 8250 drivers
internal initialisation. This led to the probe function being called
before the driver had finished its internal initialisation, causing
mayhem. Revert the ordering change.
