rust: iommu: replace core::mem::zeroed with Zeroable::zeroed

All types in `bindings` implement `Zeroable` if they can. This enables
using `Zeroable::zeroed` for `io_pgtable_cfg` initialization instead
of relying on `..unsafe { core::mem::zeroed() }`.

This change improves readability and removes an unnecessary unsafe
block.
