Subject: [PATCH] bus: fsl-mc: simplify DPRC version check

From: Ioana Ciornei <ioana.ciornei@....com>

Because the minimum supported DPRC version is 6.0, there is no need to
check for incompatible 6.x versions lower to the minimum one.  Just
remove the second half of the check to simplify the logic.
