Currently, Zephyr is always sending back notifications to
AP (e.g Linux in our case) on channel 0.
But this currently doesn't work if Linux uses other channel
id for communication. So, add option to use predefined
vring ID that can accomodate Linux used ID.

The type of the resource table is known, casting to and from void* only
hides this type which can prevent the compiler from giving helpful
warnings. One warning would have been the accidental use of
"st_resource_table" in a cast, a struct which does not exist.
Use the fw_resource_table type when dealing with resource tables.

This structure is shared between cores which may have different type
widths. Use fixed width types when defining the structure. We can
also use struct resource_table to help as it is already defined with
fixed width types and removes the need to redefine these elements.

In C++ applications, methods which are meant to be implemented in C
should be wrapped in a `extern "C"` scope at the point of declaration.
This enables the correct symbol table mangling, which fixes current
linker errors in C++.

This allows a resource table to be included even if neither virtIO nor the
RAM console are used.

The resource table is needed by the Linux kernel OS
for a rpmsg generic support, but is also recognised by OpenAMP.
This table allows to add trace based on the RAM console
and to support rpmsg protocol.
