octeontx2-af: CN10KB: fix PFC configuration

Browse source

[ Upstream commit 47bcc9c1cf ]

Suppose user has enabled pfc with prio 0,1 on a PF netdev(eth0)
	dcb pfc set dev eth0 prio-pfc o:on 1:on
later user enabled pfc priorities 2 and 3 on the VF interface(eth1)
	dcb pfc set dev eth1 prio-pfc 2:on 3:on

Instead of enabling pfc on all priorities (0..3), the driver only
enables on priorities 2,3. This patch corrects the issue by using
the proper CSR address.
