net: ipa: update table cache flushing
Update the code that causes filter and router table caches to be
flushed so that it supports IPA versions 5.0+. It adds a comment in
ipa_hardware_config_hashing() that explains that cacheing does not
need to be enabled, just as before, because it's enabled by default.
(For the record, the FILT_ROUT_CACHE_CFG register would have been
used if we wanted to explicitly enable these.)
