iommu/mediatek: Rename the register STANDARD_AXI_MODE(0x48) to MISC_CTRL
For iommu offset=0x48 register, only the previous mt8173/mt8183 use the
name STANDARD_AXI_MODE, all the latest SoC extend the register more
feature by different bits, for example: axi_mode, in_order_en, coherent_en
and so on. So rename REG_MMU_MISC_CTRL may be more proper.
This patch only rename the register name, no functional change.
