On this SoM eqos is the primary ethernet interface, Ka-Ro fuses the
address for it in eth_mac1, eth_mac2 seems to be left unfused. In their
downstream u-boot they fetch it from eth_mac1 [1][2], by setting alias
of eqos to ethernet0, the driver then fetches the mac address based on
the alias number.
Set eqos to read from eth_mac1 instead of eth_mac2. Also set fec to
point at eth_mac2 as it may be fused later even though it is disabled
by default.
With this changed barebox is now capable of loading the correct address.

While binding drivers directly to struct acpi_device objects allows
basic functionality to be provided, at least in the majority of cases,
there are some problems with it, related to general consistency, sysfs
layout, power management operation ordering, and code cleanliness.
Overall, it is better to bind drivers to platform devices than to their
ACPI companions, so convert the ACPI smart battery subsystem (SBS)
driver to a platform one.
After this conversion, acpi_smbus_hc_probe() does not need to populate the
driver_data pointer of the SMBUS HC platform device's ACPI companion any
more, so update it accordingly.
While this is not expected to alter functionality, it changes sysfs
layout and so it will be visible to user space.
