pau: link training
Add elementary functions to handle a phb complete, fundamental and
hot resets.
For the time being, specific creset and hreset are not supported.
A complete fundamental reset is based on the following steps, in this
order:
- Place all bricks into Fence state
- Disable BARs
- Reset ODL to Power-on Values
- Set the i2c reset pin in output mode
- Initialize PHY Lanes
- Deassert ODL reset
- Clear the the i2c reset pin
- Unfence bricks
- Enable BARs
- Enable ODL training mode
Link training is also set up.
