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.

Without an EXPORT_SYMBOL_GPL this is not going to be very useful for
your driver.

Unless I am missing something here, the commit that made
'pci_enable_ptm()' private didn't remove the 'EXPORT_SYMBOL' from the
function definition in drivers/pci/pcie/ptm.c.
