For LS102xA, some workarounds are only used in VER1.0, so silicon version detection are added for QDS and TWR boards.

Signed-off-by: Alison Wang alison.wang@freescale.com --- Changes in v2: - Modify the subject to describe accurately - Change SOC_VER_1_0 and SOC_VER_2_0 to SOC_MAJOR_VER_1_0 and SOC_MAJOR_VER_2_0 - Define a function instead of the piece of code which used in multiple places
