work fine on 9263ek except the IP version detection.

the at91 macb ip version is supposed to be at 0x0601010C but it's not.
At least on 9263 it's 0x0001010C. So we can not detect the arch at runtime
but we can detect that it's a macb.

So could keep the ifdef for 2 archs but use the ip version on arm
