The current driver code lacks the necessary plumbing for ACPI IDs,
preventing the mipi-i3c-hci driver from being loaded on x86
platforms that advertise I3C ACPI support.

This update adds the MIPI0100 ACPI ID to the list of supported IDs.

MIPI0100 is the ACPI ID as defined in the MIPI I3C DisCo specification.
