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

Browse Source 
[ Upstream commit 82a4e71b15 ]

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.

Fixes: 4c55215c ("qede: Add driver support for PTP")
