vchi_msg_dequeue() provides the same functionality as vchi_msg_hold()
except it copies the message data as opposed to the later which provides
the data in place.
The copying is done on a local variable, so there is no need to keep the
message out the function's bounds, so use vchi_msg_hold() instead.

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.

The idea behind this was to create an opaque handle to struct
vchiq_instance. This can be achieved without creating a new type by
means of a forward declaration of struct vchiq_instance.
This saves us from a lot of useless casting and overall simplifies code.

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.

mmal-vchiq is a reimplementation of the userland library for MMAL.
When getting a parameter, the client provides the storage and
the size of the storage. The VPU then returns the size of the
parameter that it wished to return, and as much as possible of
that parameter is returned to the client.
The implementation previously only returned the size provided
by the VPU should it exceed the buffer size. So for parameters
such as the supported encodings list the client had no idea
how much of the provided storage had been populated.

The MMAL client_component field is used with the event
mechanism to allow the client to identify the component for
which the event is generated.
The field is only 32bits in size, therefore we can't use a
pointer to the component in a 64 bit kernel.
Component handles are already held in an array per VCHI
instance, so use the array index as the client_component handle
to avoid having to create a new IDR for this purpose.

- Ignore ti-sysc clockactivity bit unless separately requested
to avoid unexpected performance issues
- Init ti-sysc framedonetv_irq to true and disable for am4
- Avoid duplicate DSS reset for legacy mode with dts data
- Remove LCD timings for am4 as they cause warnings now that we're

- Flush posted write for ti-sysc enable and disable
- Fix droid4 spi related errors with spi flags

The most anticipated fix in this pull request is probably the horrible build
fix for the RANDSTRUCT fail that didn't make -rc2. Also included is the cleanup
that removes those BUILD_BUG_ON()s and replaces it with ugly unions.
Also included is the try_to_wake_up() race fix that was first triggered by
Paul's RCU-torture runs, but was independently hit by Dave Chinner's fstest
runs as well.

A single commit that uses "arch_" atomic operations to avoid the
instrumentation that comes with the non-"arch_" versions. In preparation
for that commit, it also has another commit that makes these "arch_"
atomic operations available to generic code.
Without these commits, KCSAN uses can see pointless errors.
Both from Peter Zijlstra.
