There aren't enough resources to run these ports at 10G speeds. Disable
10G for these ports, reverting to the previous speed.

Fixes: 36926a7d70c2 ("powerpc: dts: t208x: Mark MAC1 and MAC2 as 10G")
Reported-by: Camelia Alexandra Groza <camelia.groza@nxp.com>
Signed-off-by: Sean Anderson <sean.anderson@seco.com>

Changes in v2:
- Remove the 10g properties, instead of removing the MAC dtsis.

I see the patch marked Not Applicable in the netdev patchwork.
What tree will it go through?

I could be wrong but I think DTS patches are supposed to go via the
platform / arch trees. We mostly take bindings via the networking trees
(and DTS changes if they are part of a larger code+binding+dts set).
But we can obviously apply this patch if that's the preference of
the PowerPC maintainers..

The commit it Fixes went in via the networking tree, so I think it would
make sense for you to take this also via the networking tree.

cheers
