774397b332 drivers/reset: Add line read-back and a procfs entry.
status() reads one reset line at a time, and only for a caller that
already knows the id.  Nothing else in the interface says how many lines
a controller has or what any of them resets, so the lines a board is
holding cannot be surveyed.

Adds an optional get_line method describing one line as a structure: its
name, and a text member for controller specific fields the structure
does not cover.  The asserted state stays with status(), which already
reports it, so a controller does not supply the same fact twice.
Returning -ENODEV reports an id that names no line, which is how
controllers with gaps in their numbering are handled.
reset_controller_dev gains the line count that bounds the ids.

CONFIG_RESET_PROCFS adds /proc/reset, one key:value line per reset line,
every line the same tokens in the same order so the file is machine
parseable.  A controller without get_line is listed by name and a note.

The controller list already existed for reset_control_get() to search,
so the renderer only walks what was there.  /proc/reset is claimed when
the first controller registers; procfs_register() requires that procfs
is not yet mounted, which holds because controllers register during
board or architecture start up, and it appends without checking for
duplicates, so the entry is claimed once for the lifetime of the system.

Documents the framework, which had a page with nothing on it: the
consumer interface and what shared and exclusive handles mean, the
controller interface, the new method, and /proc/reset.

Off by default and costs nothing when off.  No in-tree configuration
enables RESET, so this builds only when a board turns it on.

0dccc8ba21 include/debug.h: Move to include/nuttx/debug.h
debug.h is a NuttX-specific, non-POSIX header. Placing it in the
top-level include/ directory creates naming conflicts with external
projects that define their own debug.h.
This commit moves the canonical header to include/nuttx/debug.h,
following the NuttX convention for non-POSIX/non-standard headers,
and updates all in-tree references.

A backward-compatibility shim is left at include/debug.h that
emits a deprecation #warning and re-includes <nuttx/debug.h>,
allowing out-of-tree code to continue building while migrating.

dcea1b90e7 arch_atomic: only support atomic_xx and atomic64_xx function
Modify the kernel to use only atomic_xx and atomic64_xx interfaces,
avoiding the use of sizeof or typeof to determine the type of
atomic operations, thereby simplifying the kernel's atomic
interface operations.
