Subject: [PATCH] [chassis][voq] Remove the leaf ref for the ifname in
 sonic-system-port.yang (#18855)

Microsoft ADO 27934751:

Fixes #18854

Update the sonic-system-port.yang to remove the check to have ifname as leafref in the port table
The system-port config table will have all the ports in the chassis not only to one linecard, so in case of the chassis with different linecards sku with different number of ports this leafref will not work.
