octeontx2-af: Bringup CGX LMAC links by default
- Added new CGX firmware interface API for sending link up/down
commands
- Do link up for cgx lmac ports by default at the time of CGX
driver probe. Since cgx link up in driver probe affects the
Linux boot time, linkup procedure is kept threaded using
workqueues.
For this, a new cgx API cgx_lmac_linkup_start has been added.
