powerpc/pmap: Add pmap_sync_icache() for radix pmap

DTrace pid provider writes to user space to set breakpoints.  Failing to
sync the icache can lead to SIGTRAP.  Radix pmap is the only one missing
a pmap_sync_icache() method, so the pid provider would only potentially
crash a process on a POWER9 or later system.
