We've got a separate option to configure the accelerator nowadays, which
is shorter to type and the preferred way of specifying an accelerator.
Use it in the source and examples to show that it is the favored option.
(However, do not touch the places yet which also specify other machine
options or multiple accelerators - these are currently still better
handled with one single "-machine" statement instead)

Thanks. While "-accel kvm:tcg" is not going to be supported, the above
replacement are all good.

I guess we should really do something about that before people start
using it in the wild...

-accel is yet another convenience option. We have so many of them. I
dislike the complexity they add to the CLI. Here's how this one got in:

tcg: add options for enabling MTTCG
We know there will be cases where MTTCG won't work until additional work
is done in the front/back ends to support. It will however be useful to
be able to turn it on.
As a result MTTCG will default to off unless the combination is
supported. However the user can turn it on for the sake of testing.

Not a peep on why the existing options are so insufficient we must have
another one.
Our CLI will remain the steaming mess it has become until we reform the
habits that got us there.
No objection to your patch.

-accel's accel suboption is currently defined as a convenience option,
but it shouldn't be. It's the older "-M accel=foo:bar" that should
become "-accel foo -accel bar" and -accel then is the preferred way.
The existing option "-M accel" was insufficient because it didn't allow
accelerator-specific suboptions; they were all over the place ("-machine
kernel_irqchip", "-tb-size", etc.) and indeed mostly in wrong places.
