We use dma_get_mask() of auxdev device for calculate iova pfn limit.
This is always 32 bit mask as we do not initialize the mask (and we can
not do so, since dev->dev_mask is NULL anyways for auxdev).

Since we need 31 bit mask for non-secure mode use mmu_info->aperture_end
which is properly initialized to correct mask for both modes.

Fixes: daabc5c64703 ("media: ipu6: not override the dma_ops of device in driver")
