[PATCH memory-model 06/14] tools/memory-model: Remove ACCESS_ONCE() from model

[Paul E. McKenney]

From: Mark Rutland <mark.rutland@xxxxxxx>

Since commit:

  b899a850431e2dd0 ("compiler.h: Remove ACCESS_ONCE()")

... there has been no definition of ACCESS_ONCE() in the kernel tree,
and it has been necessary to use READ_ONCE() or WRITE_ONCE() instead.

Correspondingly, let's remove ACCESS_ONCE() from the kernel memory
model.
