…iver data

This simplifies getting the 'driver_data' from 'struct device' directly.
Going through platform_device or pci_dev is not required. Also removes
condition check as the private data stored with dev pointer, means
irrespective of enumeration mode, we can use dev_get_drvdata().
This removes the unnecessary step back and forth.
