ata: libahci: Use of_platform_device_create only if supported
of_platform_device_create does not exist if OF_ADDRESS is not configured,
so limit its use accordingly.
Without this fix, the sparc64:allmodconfig build fails with
ERROR: "of_platform_device_create" [drivers/ata/libahci_platform.ko] undefined!
Fixes: c7d7ddee7e24 ("ata: libahci: Allow using multiple regulators")
