ti: k3: common: Mark sections for AM65x coherency workaround
These sections of code are only needed for the coherency workaround used for AM65x, if this workaround is not needed then this code is not either. Mark it off to keep it separated from the rest of the PSCI implementation. Signed-off-by: Andrew F. Davis <afd@ti.com> Change-Id: I113ca6a2a1f7881814ab0a64e5bac57139bc03ef
