board/freescale: Move CRC32 offset in NXID v1 data format
According to AN3638, CRC of NXID v1 is at the end of the 256-byte I2C memory. The wrong CRC32 offset prevents Uboot from reading system information from EEPROM. No NXID v0 is being used on Freescale boards. Signed-off-by: Ebony Zhu <b45385@freescale.com> Reviewed-by: York Sun <yorksun@freescale.com>
