Subject: [PATCH v2 1/3] ARM: dts: imx51: ZII: Add missing phy-mode

The DSA framework has got more picky about always having a phy-mode
for the CPU port. The imx51 Ethernet supports MII, and RMII. Set the
switch phy-mode based on how the SoC Ethernet port has been
configured.

Additionally, the cpu label has never actually been used in the
binding, so remove it.

v2: Use rev-mii for the side 'playing PHY'.
