Some platforms(ex: mt6779) need to improve performance by setting
REG_MMU_WR_LEN register. And we can use WR_THROT_EN macro to control
whether we need to set the register. If the register uses default value,
iommu will send command to EMI without restriction, when the number of
commands become more
