drivers: use node IDs for DEVICE_MMIO.*_INIT

Browse source 
There is nothing wrong with instance numbers and they are
recommended for use whenever possible, but this is an API
design problem because it's not always possible to get nodes
by instance number; in some cases, drivers need to get node
identifiers from node labels, for example.

Change these APIs (which are not yet in any Zephyr release)
to take node IDs instead of instance IDs.

Fixes: #26984
