Subject: [PATCH 1/5] i3c: mipi-i3c-hci: Add MIPI0100 ACPI ID to the I3C Support List

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.

Signed-off-by: Shyam Sundar S K <Shyam-sundar.S-k@....com>

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