[PATCH] Check return status of register calls in i82365

i82365 calls driver_register and platform_device_register without checking
their return values.  This patch fixes that.

It also runs platform_device_register() prior to isa_probe() so we don't have
to undo ise_probe()'s effects if platform_device_register() ends up failing.
