i3c: renesas: Update HW registers after SW computations are done

renesas_i3c_bus_init() performs a number of computations and software
cache updates, interleaving them with hardware register writes. While
this works today, it makes it harder to minimize the time the controller
must remain powered when runtime PM is introduced.

Perform all software computations and cache updates first, then update
the hardware registers. This prepares for future runtime PM support.
