Starfive JH7110 needs to clear L2 LIM to zero before use or ECC error
would be triggered. Currently, we use DDR ram for SPL malloc arena on
Visionfive 2 board in defconfig, but it's also possible to use L2 LIM as
SPL malloc arena. To avoid triggering ECC error in this scenario, we
imply SPL_SYS_MALLOC_CLEAR_ON_INIT as default.
