driver: fsl-mc: qbman: Add QBMAN 4.1 support
LS2080A SoC family has QBMAN ver 4.0 whereas newer
SoCs like LS2088A, LS1088A has QBMAN ver 4.1
QBMAN ver 4.0 and ver 4.1 supports dqrr size as 4 and 8 respectively.
Add support of
to check QBMAN version based on SoC SVR
update dqrr_size accordingly
update code to support larger dqrr_size
