[PATCH v2 26/27] locking/atomic: docs: Add atomic operations to the driver basic API documentation

[Mark Rutland]

From: "Paul E. McKenney" <paulmck@xxxxxxxxxx>

Add the generated atomic headers to driver-api/basics.rst in order to
provide documentation for the Linux kernel's atomic operations.

At the same time, dtop the x86 atomic header, which provides kerneldoc
comments for some arch_atomic*_*() operations. The arch_atomic*_*()
operations are now purely an implenentation detail of the
raw_atomic*_*() ops, and outside of implementing the atomics, code
should use the raw_atomic*_*() forms.
