[U-Boot] [PATCH 4/4] arm: ls102xa: Add SystemID EEPROM support for LS1021ATWR board

[Alison Wang]

SystemID information could be read through I2C1 from EEPROM
on LS1021ATWR board.

As LS1 is a little-endian processor, getting the version ID by
be32_to_cpu() is wrong. Fix it by using e.version directly.
This change will be compatible for both ARM and PowerPC.
