85xx: Socrates: Major code update.

- Update the local bus ranges in the FDT for Linux for the various
  devices connected to the local bus via chip-select.

- Set the LCRR_DBYP bit in the LCRR for local bus frequencies
  lower than 66 MHz and uses I/O accessor functions consequently.

- UPM data update.

- Update of default environment and configuration.  Use I2C multibus
  as we do have two I2C buses.  Also enable sdram and ext2 commands.
