component: do not dereference opaque pointer in debugfs
The match data does not have to be a struct device pointer, and indeed very often is not. Attempt to treat it as such easily results in a crash. For the components that are not registered, we don't know which device is missing. Once it it is there, we can use the struct component to get the device and whether it's bound or not.
