dm: ns16550: Correct the probe logic for platform data

Browse source 
The probe logic sets up the pointer to the platform data in the device
tree decode method. It should be done in the probe() method, and anyway
the device tree decode method can't be used when CONFIG_OF_CONTROL is
not enabled.

Fix these two problems.
