Most C drivers use a pointer (and cast to kernel_ulong_t) for driver_data
fields in device_id. Rust code currently does not do this, but rather use
indices. These indices then needs to be translated to `&IdInfo` separately
and this is by a side table.

This leads to open-coded ACPI/OF handling in driver.rs, which is not
desirable. Convert the code to use pointers (or rather, static references)
instead.

Changes in v2:
- Change USB to take `Option<&IdInfo>` in addition to PCI due to ability to
  dynamically add IDs.
- Mention dyn IDs and driver_override in safety comments and justify why
  they're correct.
- Link to v1: https://patch.msgid.link/20260618-id_info-v1-0-96af1e559ef9@garyguo.net
