Merge branch 'net-dsa-microchip-dcb-fixes'

Oleksij Rempel says:

====================
net: dsa: microchip: DCB fixes

This patch series address recommendation to rename IPV to IPM to avoid
confusion with IPV name used in 802.1Qci PSFP. And restores default "PCP
only" configuration as source of priorities to avoid possible
regressions.
