net: mvpp2: fix 10 Mbit/s usage
This commit is similar to commit 4d12bc63ab5e ("net: mvneta: fix operation in 10 Mbit/s mode"), but this time for the mvpp2 driver. The driver was properly taking into account the 1 Gbit/s and 100 Mbit/s speeds, but not the 10 Mbit/s, which was handled as 100 Mbit/s. However, the MVPP2_GMAC_CONFIG_MII_SPEED bit in the MVPP2_GMAC_AUTONEG_CONFIG register must remain cleared to allow 10 Mbit/s operation. This commit therefore fixes 10 Mbit/s operation.
