powerpc: dts: t208x: Disable 10G on MAC1 and MAC2

[ Upstream commit 8d8bee13ae9e316443c6666286360126a19c8d94 ]

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")
