[U-Boot] [PATCH] driver: net: fsl-mc: Update fsl_mc_ldpaa_exit() path
Earlier when MC is loaded but DPL is not deployed results in FDT fix-up code execution hang. For this case now print message on console and returns success instead of return -ENODEV. This update allows to continue fdt fixup execution.
