[U-Boot] [PATCH 10/22][v2] board/fsl/common: Fix eeprom system version endianness

From: Jaiprakash Singh <b44839@freescale.com>

SYSTEM ID EPPROM always store SYSTEM version info in big endian format.
SoC with ARM or PowerPC core should read/write version info from eeprom
in BIG endian format.

So use cpu-specific APIs to read SYSTEM version.
