ARM: 7884/1: mm: Fix ECC mem policy printk
ECC policy can be applied to the whole system when this bit is implemented by SoC vendor (IMP - bit 9 - in L1 page table entry format). When this bit is not implemented by SoC vendor it doesn't mean that system has no other way how to do ECC. This patch ensures to show this message only when ECC is requested via cmd line ecc=on and runs on appropriate ARM core.
