[U-Boot] [PATCH][v2] driver: net: fsl-mc: Update fsl_mc_ldpaa_exit() path

[Yogesh Gaur]

When MC is loaded, but DPL is not deployed, it results in FDT fix-up
code execution hang.
To resolve this, returns success instead of return -ENODEV and print message
on console.
This update allows to continue fdt fixup execution.
