All the functions that vchi currently provides are a 1:1 mapping to its
vchiq counterparts. Get rid of vchi altogether and use vchiq's on all
services.
In the process also get rid of the vchi directory, as the only remaining
file was a TODO file, which now lives in the parent directory.

We can't really merge it with vchiq_queue_message() as it has internal
users that will not benefit from the retry mechanism
vchiq_queue_kernel_message() uses. So, for the sake of getting rid of
vchi, move it into vchiq.

Its vchiq counterpart, vchiq_bulk_transmit() is only used by vchi. We
can then merge both functions by moving vchi_bulk_queue_transmit()'s
retry mechanism into vchiq_bulk_transmit() and let services call the
later.

The services have access to struct vchiq_header's internals, so we can
let them get the data pointer. This pretty much makes both functions
exactly the same, which will allow us to make a switch to
vchiq_msg_hold() further down the road.

vchi created an opaque structure to be held by services while they
process callback messages. The contents of this opaque structure are the
service handle, which all services already maintain, and a pointer to
vchiq's message structure, struct vchiq_header.
Let's get rid of this opaque structure and directly pass struct
vchiq_header, which is what ultimately vchiq consumes when handling
callback messages.

As vchiq_shim's callback does nothing aside from pushing messages into
the service's queue, let's bypass it and jump directly to the service's
callbacks, letting them choose whether to use the message queue.
It turns out most services don't need to use the message queue, which
makes for simpler code in the end.

The idea behind struct vchi_service_handle is to create an opaque handle
to struct shim_service. This can be achieved by doing a forward
declaration of struct shim_service, which will avoid unwarranted casts
and pointer play.
Ultimately as a rename is due all over the vchi user space, rename
struct shim_service into struvt vchi_service, which is more consistent
with the rest of the exposed API.

There already is a function that covers most of the functionality
vchi_msg_peek() provides: vchi_msg_hold(). The main difference being
that the later removes the message from vchu's queue while the other
does it later on, while releasing the message.
There are no users of this function that can't be trivially converted to
vchi_msg_hold(). So, for the sake of removing duplicate code, get rid of
vchi_msg_peek().
Note that the opposite change could be performed as well. But
vchi_msg_peek()'s implementation was deemed less robust as messages have
to be released in order.

Now that the SPDX tag is in all vc04_services files, that identifies the
license in a specific and legally-defined manner. So the extra GPL and
BSD text wording can be removed as it is no longer needed at all.
This is done on a quest to remove the 700+ different ways that files in
the kernel describe the license text.
No copyright headers or other non-license-description text was removed.
