af20208cd9 devices: mark device MMIO declarations to boot/pinned sections 
This adds to the macros for device MMIO declaration so they can
be put into  boot or pinned linker sections as needed.

d2ad783a97 mmu: rename z_mem_map to z_phys_map 
Renamed to make its semantics clearer; this function maps
*physical* memory addresses and is not equivalent to
posix mmap(), which might confuse people.

mem_map test case remains the same name as other memory
mapping scenarios will be added in the fullness of time.

Parameter names to z_phys_map adjusted slightly to be more
consistent with names used in other memory mapping functions.

5e0b55c30e kernel: demote k_mem_map to z_mem_map 
Memory mapping, for now, will be a private kernel API
and is not intended to be application-facing at this time.

9247e8bc44 code-guideline: Tag name should be a unique identifier 
Following are the changes to variable names that are matching
with tag names (Rule 5.7 violations)

In kernel.h, event_type is matching with a tag name in
lib/os/onoff.c. Added a _ prefix to event_type and
also to the macro argument names.

In userspace.c, *dyn_obj is matching with the tag name
dyn_obj in the file itslef. Changed it to dyn

In device.h, device_mmio.h, init.h and init.c,
changed the *device to dev. Except for one change in
init.h

63c3e153d6 drivers: use node IDs for DEVICE_MMIO.*_INIT 
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

db0ca08fb7 kernel: add macros for device MMIO management 
Three variants provided:

- Drivers with one MMIO region to manage
- Drivers with multiple MMIO regions to manage
- Drivers or driver-like code which doesn't use Zephyr's device
  model
