Bool symbols implicitly default to 'n'.
A 'default n' could make sense e.g. in a Kconfig.defconfig file, if you
wanted to override a 'default y' on the base definition of the symbol,
but it doesn't seem to be used like that on any of these symbols.

Introduce a Kconfig option (CONFIG_OPENAMP_SRC_PATH) that allows us to
point to an external copy of open-amp.

With recent changes to open-amp we can now include and build it directly
as a zephyr library rather than doing a recursive make. We remove
ext/lib/ipc/open-amp.cmake as part of this change and introduce a
Kconfig option for open-amp.
Fixes: #7673

Pull in a slightly more recent version of open-amp with changes
to the build system to improve integration with Zephyr. The recent
changes let us embedded open-amp without having to use recursive
building.

Move open-amp to be in ext/lib/ipc/open-amp/open-amp. This allows us to
be Zephyr specific files and config like README (for import),
CMakeLists.txt file, Kconfig, etc in ext/lib/ipc/open-amp/ that don't
conflict with any files that might have the same name in
ext/lib/ipc/open-amp/open-amp.

With recent changes to libmetal we can now include and build it directly
as a zephyr library rather than doing a recursive make. We remove
ext/hal/libmetal.cmake as part of this change and introduce a Kconfig
option for libmetal.
This is a partial fix for issue #7673.

libmetal itself isn't an ipc library, its a generic HAL abstraction
library so move it into ext/hal where it belongs.

When we import open-amp we removed the apps dir to reduce the amount
of code imported.
Purpose:
IPC layer that implements rpmsg communication between cores.
Description:
This repository is the home for the Open Asymmetric Multi Processing
(OpenAMP) framework project. The OpenAMP framework provides software
components that enable development of software applications for
Asymmetric Multiprocessing (AMP) systems. The framework provides the
following key capabilities.
* Provides Life Cycle Management, and Inter Processor Communication
capabilities for management of remote compute resources and their
associated software contexts.
* Provides a stand alone library usable with RTOS and Baremetal software
environments
* Compatibility with upstream Linux remoteproc and rpmsg components
* Following AMP configurations supported:
a. Linux master/Generic(Baremetal) remote
b. Generic(Baremetal) master/Linux remote
* Proxy infrastructure and supplied demos showcase ability of proxy on
master to handle printf, scanf, open, close, read, write calls from
Bare metal based remote contexts.
Dependencies:
libmetal (https://github.com/OpenAMP/libmetal) - provides HAL layer
between OpenAMP and RTOS or OS environment.

When we import libmetal we removed the tests/ and examples/ dir to
reduce the amount of code imported.
Purpose:
HAL abstraction layer used by open-amp
Description:
Libmetal provides common user APIs to access devices, handle device
interrupts and request memory across the following operating
environments:
* Linux user space (based on UIO and VFIO support in the kernel)
* RTOS (with and without virtual memory)
* Bare-metal environments
Dependencies:
Depends on Zephyr itself as it utilizes Zephyr's APIs to provide an
abstraction to open-amp.
