serdev: do not generate modaliases for controllers
Serdev controllers are not bound to any drivers and it therefore makes no sense to generate modaliases for them. This has already been fixed separately for ACPI controllers for which uevent errors were also being logged during probe due to the missing ACPI companions (from which ACPI modaliases are generated). This patch moves the modalias handling from the bus type to the client device type. Specifically, this means that only serdev devices (a.k.a. clients or slaves) will have have MODALIAS fields in their uevent environments and corresponding modalias sysfs attributes. Also add the missing static keyword for the modalias device attribute when moving the definition.
