armv7: LS1021a: enable i-cache in start.S
Delete CONFIG_SKIP_LOWLEVEL_INIT define in ls1021atwr.h and ls1021aqds.h can let it run cpu_init_cp15 to enable i-cache. First stage of u-boot can run faster after that. There is a description about skip lowlevel init in board/freescale/ls1021atwr/README. Signed-off-by: Xiaoliang Yang <xiaoliang.yang@nxp.com> Reviewed-by: York Sun <york.sun@nxp.com>
