qede: Adverstise software timestamp caps when PHC is not available.



[ Upstream commit 82a4e71b1565dea8387f54503e806cf374e779ec ]

When ptp clock is not available for a PF (e.g., higher PFs in NPAR mode),
get-tsinfo() callback should return the software timestamp capabilities
instead of returning the error.
