[PATCH 2/2] ax88796: Add method to take MAC from platform data

[Daniel Mack]

Implement a way to provide the MAC address for ax88796 devices from
their platform data. Boards might decide to set the address
programmatically, taken from boot tags or other sources.

Please note that in contrast to the version I posted here previously,
this patch does not use platform_get_irq_flags() anymore. Nobody seemed
interested in the patch I sent along to implement that in
drivers/base/platform.c, so I gather the flags manually from this driver
now, using platform_get_resource().
