i3c: master: Introduce optional Runtime PM support
Master drivers currently manage Runtime PM individually, but all require
runtime resume for bus operations. This can be centralized in common code.
Add optional Runtime PM support to ensure the parent device is runtime
resumed before bus operations and auto-suspended afterward.
Notably, do not call ->bus_cleanup() if runtime resume fails. Master
drivers that opt-in to core runtime PM support must take that into account.
Also provide an option to allow IBIs and hot-joins while runtime suspended.
