Subject: [PATCH 01/13] soc/fsl/qman: fixup liodns only on ppc targets

From: Laurentiu Tudor <laurentiu.tudor@....com>

ARM SoCs use SMMU so the liodn fixup done in the qman driver is no
longer making sense and it also breaks the ICID settings inherited
from u-boot. Do the fixups only for PPC targets.
