iommu/mediatek: Fix crash on isr after kexec()
If the system is rebooted via isr(), the IRQ handler might
be triggered before the domain is initialized. Resulting on
an invalid memory access error.
Fix:
[ 0.500930] Unable to handle kernel read from unreadable memory at virtual address 0000000000000070
[ 0.501166] Call trace:
[ 0.501174] report_iommu_fault+0x28/0xfc
[ 0.501180] mtk_iommu_isr+0x10c/0x1c0
