[POWERPC] add check for initialized driver data to pmi driver
This patch adds a check for the private driver data to be initialized. The bug showed up, as the caller found a pmi device by it's type. Whereas the pmi driver probes for the type and the name. Since the name was not as the driver expected, it did not initialize. A more relaxed probing will be supplied with an extra patch, too.
