Stefan Roese 303dfc2e5e x86: conga-qeval20-qa3: Add SMBus support and SMSC2513 config code 
This patch includes the following changes:

- Remove Designware I2C support from dts as its not used
- Configure SMBus PADs in dts
- Enable I2C commands and I2C support
- Configure SMSC2513 USB hub via SMBus upon startup
- Move environment location to match Minnowmax example
- Enhancement of the default environment
