net: fec: limit register access on i.MX6UL
Using 'ethtool -d […]' on an i.MX6UL leads to a kernel crash:
Unhandled fault: external abort on non-linefetch (0x1008) at […]
due to this SoC has less registers in its FEC implementation compared to other
i.MX6 variants. Thus, a run-time decision is required to avoid access to
non-existing registers.
Fixes: a51d3ab50702 ("net: fec: use a more proper compatible string for i.MX6UL type device")
