i2c: powermac: replace deprecated strncpy

`strncpy` is deprecated for use on NUL-terminated destination strings [1].

We should prefer more robust and less ambiguous string interfaces.

`info.type` is expected to be NUL-terminated judging by its use in
`i2c_new_client_device()` wherein it is used to populate `client->name`:
|	strscpy(client->name, info->type, sizeof(client->name));

NUL-padding is not required and even if it was, `client` is already
zero-initialized.

Considering the two points from above, a suitable replacement is
`strscpy` [2] due to the fact that it guarantees NUL-termination on the
destination buffer without unnecessarily NUL-padding.
