Subject: [PATCH] powerpc: dts: p2020rdb: add missing peripherials

This patch adds dts entry for some peripherials:
- i2c: temperature sensor ADT7461
- i2c: eeprom m24256
- i2c: eeprom at24c01
- i2c: pmic zl2006
- i2c: gpio expander
- phy: reset pins for phy
- dsa: switch vsc7385

It was required to adjust rgmii settings for enet0 because switch with
dsa driver act different without 8081 sterring.
