[U-Boot] [PATCHv6 16/28] fdt: fixup_eth: Remove code duplication with a function

[Olliver Schinagl]

In fdt_support.c we use a loop to parse the mac address string from the
fdt blob, net.h has a function for this however, so lets use it.

Also, rename the variable from tmp to something more descriptive.
