[Shengzhou] so far DS1307 and DS1374 occur only on those boards with corenet64. 
CONFIG_RTC_DRV_CMOS is enabled in mpc85xx_defconfig, mpc85xx_smp_defconfig, corenet32_smp_defconfig, etc, here keeps consistent in corenet64.
It seems CONFIG_RTC_DRV_CMOS is not needed on 85xx platform, do we need to remove CONFIG_RTC_DRV_CMOS from all 85xx/corenet defconfig? If so, I will post a new patch to do it.
