net/qede/base: add feature support for per-PF virtual link

Browse Source 
Add per-PF virtual link support.
This feature adds a logical layer over the physical link to reflect the
control of OEM management protocols either thru' sideband or a switch.
For example, a switch could send a link-down tlv for a PF and this will
put down logical link and virtual link in shared mem (SHMEM) for that PF
inspite of physical link being up for that port.
