platform/x86: intel: Move debugfs register before creating devices

Browse Source 
It is possible that the driver handling device is enumerated before
registering debugfs. If the driver wants to access debugfs by calling
tpmi_get_debugfs_dir(), this will return error in this case.

Hence register debugfs before creating devices.
