i3c: mipi-i3c-hci: Add optional Runtime PM support

Browse source

Implement optional Runtime PM support for the MIPI I3C HCI driver.
Introduce runtime suspend and resume callbacks to manage bus state and
restore hardware configuration after resume.  Optionally enable autosuspend
with a default delay of 1 second, and add helper functions to control
Runtime PM during probe and remove.

Read quirks from i3c_hci_driver_ids[] and set new quirk
HCI_QUIRK_RPM_ALLOWED for intel-lpss-i3c devices to enable runtime PM for
them.
