net: dsa: bcm_sf2: Allow non-IMP ports to have Broadcom tags enabled
Parse the "brcm,use-bcm-hdr" boolean property during ports
identification to fill a bitmask of ports that should have Broadcom tags
enabled. This is needed in some configurations where per-packet metadata
can be exchanged using Broadcom tags between the switch and an on-chip
acceleration device.
