[ Upstream commit 8a00fc606312c68b98add8fe8e6f7a013ce29e78 ]
Not just i.MX8M, but all i.MX6/7 (and subtypes) need to reverse the
MAC address read from fuses. Exceptions are i.MX6SLL and i.MX7ULP which
do not support ethernet at all.
Fixes: d0221a780cbc ("nvmem: imx-ocotp: add support for post processing")
