[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.
