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.
