Make pci_enable_ptm() accessible from the drivers.

Even if PTM still works on the platform I am using without calling
this function, it might be possible that it's not always the case.

Exposing this to the driver enables the driver to use the
'ptm_enabled' field of 'pci_dev' to check if PTM is enabled or not.

This reverts commit ac6c26da29c12fa511c877c273ed5c939dc9e96c.
