Subject: [PATCH net v2] powerpc: dts: t208x: Disable 10G on MAC1 and MAC2

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@....com>
Signed-off-by: Sean Anderson <sean.anderson@...o.com>
---

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