pwm-tegra is a platform driver, but for drivers on hot-pluggable buses we still
want bind/unbind for testing, even if we opt-out from driver_override.

Besides that, I think that even for buses that do not have hotplug, there are
cases where it can be useful to be able test whether a driver survives
bind/unbind (i.e. follows the device driver lifecycle rules). E.g. because the
same IP will later receive an implementation on a hot-pluggable bus that shares
driver code, or just to validate driver design in general.
