Martí Bolívar 7e0eed9235 devicetree: allow access to all nodes
Usually, we want to operate only on "available" device
nodes ("available" means "status is okay and a matching binding is
found"), but that's not true in all cases.

Sometimes we want to operate on special nodes without matching
bindings, such as those describing memory.

To handle the distinction, change various additional devicetree APIs
making it clear that they operate only on available device nodes,
adjusting gen_defines and devicetree.h implementation details
accordingly:

- emit macros for all existing nodes in gen_defines.py, regardless
  of status or matching binding
- rename DT_NUM_INST to DT_NUM_INST_STATUS_OKAY
- rename DT_NODE_HAS_COMPAT to DT_NODE_HAS_COMPAT_STATUS_OKAY
- rename DT_INST_FOREACH to DT_INST_FOREACH_STATUS_OKAY
- rename DT_ANY_INST_ON_BUS to DT_ANY_INST_ON_BUS_STATUS_OKAY
- rewrite DT_HAS_NODE_STATUS_OKAY in terms of a new DT_NODE_HAS_STATUS
- resurrect DT_HAS_NODE in the form of DT_NODE_EXISTS
- remove DT_COMPAT_ON_BUS as a public API
- use the new default_prop_types edtlib parameter

Tomasz Bursztyka 97326c0445 device: Fix structure attributes access
Since struct devconfig was merged earlier into struct device, let's fix
accessing config_info, name, ... attributes everywhere via:

grep -rlZ 'dev->config->' | xargs -0 sed -i 's/dev->config->/dev->/g'

Kumar Gala 0a7d4e2135 devicetree: Change DT_FOREACH_IMPL_ to not insert semicolon
Remove semicolon between instance invocations of DT_FOREACH_IMPL_ and
thus DT_INST_FOREACH.  This provides more flexibility to the user.  This
requires we fixup in tree users to add semicolon where needed.
