i3c: mipi-i3c-hci: Add a quirk to set PIO mode
The AMD HCI controller currently only supports PIO mode but exposes DMA
rings to the OS, which leads to the controller being configured in DMA
mode. To address this, add a quirk to avoid configuring the controller in
DMA mode and default to PIO mode.
Additionally, introduce a generic quirk infrastructure to the mipi-i3c-hci
driver to facilitate seamless future quirk additions.
