Martí Bolívar 2c99173d64 Revert "device: simplify structure of handles array"
This reverts commit ec331c6fe2.

Although it's a valid simplification under the assumption that we're
going to be padding the array out anyway, it would use extra ROM if we
fix the build system issues that are currently forcing gen_handles.py
to introduce extra padding in the handles arrays for linker pass 2.

On the (perhaps optimistic) assumption that we're going to fix the
build system, let's get rid of a commit that would get in the way. The
extra "complexity" in device_required_handles_get() is trivial.

This gets rid of a comment describing the linker passes, but the
structure of the comment is a bit misleading (and it contains
incorrect information for the results of pass 2: the terminator at the
end is DEVICE_HANDLE_ENDS, not DEVICE_HANDLE_NULL).

The Zephyr Project is a scalable real-time operating system (RTOS) supporting
multiple hardware architectures, optimized for resource constrained devices,
and built with security in mind.

The Zephyr OS is based on a small-footprint kernel designed for use on
resource-constrained systems: from simple embedded environmental sensors and
LED wearables to sophisticated smart watches and IoT wireless gateways.

The Zephyr kernel supports multiple architectures, including ARM Cortex-M,
Intel x86, ARC, Nios II, Tensilica Xtensa, and RISC-V, and a large number of
`supported boards`_.
