iommu/mediatek: Remove for_each_m4u in tlb_sync_all
The tlb_sync_all is called from these three functions:
a) flush_iotlb_all: it will be called for each a iommu HW.
b) tlb_flush_range_sync: it already has for_each_m4u.
c) in irq: When IOMMU HW translation fault, Only need flush itself.
Thus, No need for_each_m4u in this tlb_sync_all. Remove it.
