Should be __devinit .

I prefer to have it as follows (so that the driver.owner field is also set):
static struct platform_driver ar7_wdt_driver = {
	.probe = ar7_wdt_probe,
	.remove = __devexit_p(ar7_wdt_remove),
	.driver = {
		.owner = THIS_MODULE,
		.name = "ar7_wdt",
	},
};

I suggest to also change the reboot notifier code into a platform shutdown method.
You then get something like the attached patch (untested, uncompiled and I included above 2 remarks).
For the rest: code is OK for me. After the __init to __devinit fix you can add my signed-off-by.

Kind regards,
Wim.
