Drop __init usage throughout this patch please.

Please tab these out properly And also leave off the , after the
init function.

Let's keep this taking the platform device pointer. That way in
the future devm could be used as well as other platform device
APIs without having to change all init signatures.

Can use of_device_get_match_data() instead

It would be pretty nice if we could have some platform driver
common function for this where we want to call different probe
functions for different compatible ids and put them all in the
same driver file. Like platform_driver_of_probe() or something
that then calls a int (*init_func)(struct platform_device *pdev)
directly from the of match table for you.
