Implement the gettimexattrs64 callback in the ENA driver to support
the PTP_SYS_OFFSET_EXTENDED_ATTRS ioctl.
This enables applications to retrieve PHC timestamps with quality
attributes through the standard PTP ioctl interface.
The ENA device currently reports only error_bound (valid bit set).
Other attributes are not reported (valid bits unset).
Typically it would be a policy not to introduce new attributes which are
not yet used, and add the other attributes once a user appears. However,
I think it makes sense to have the full set of desired attributes
especially given the ioctl interface limitations which would otherwise
require a lot of reserved space or new ioctl numbers. Especially given
the uAPI here has been discussed and changed heavily from previous patch
iterations.
