Use the common GSC driver. This allows us to do some additional cleanup: - use the GSC driver functions - move waiting for the EEPROM to the SPL int (it will always be ready after this) - move eeprom functions into eeprom file and elimate GSC_I2C_BUS - eliminate some redundant EEPROM reads (the EEPROM must be read in SPL before relocation, in SPL after relocation, and in U-Boot init. All subsequent uses can use the global structure) - remove unnecessary header files and alphabatize includes Signed-off-by: Tim Harvey <tharvey@gateworks.com>
