i3c: mipi-i3c-hci: Add support for MIPI I3C HCI on PCI bus

[ Upstream commit 30bb1ce71215645fa6a92f4fa8cbb8f58db68f12 ]

Add a glue code for the MIPI I3C HCI on PCI bus with Intel Panther Lake
I3C controller PCI IDs.

MIPI I3C HCI on Intel platforms has additional logic around the MIPI I3C
HCI core logic. Those together create so called I3C slice on PCI bus.
Intel specific initialization code does a reset cycle to the I3C slice
before probing the MIPI I3C HCI part.
