[PATCH v2 1/3] ppc: define sync_caches_for_execution only for MPC85xx

[Ahmad Fatoum]

From: Ahmad Fatoum <a.fatoum at barebox.org>

In preparation for adding a call to sync_caches_for_execution() into
common code, make sure PowerPC configurations without an out-of-line
definition fallback to the inline no-op definition.
