net: ipa: kill FILT_ROUT_CACHE_CFG IPA register
A recent commit defined a few IPA registers used for IPA v5.0+.
One of those was a mistake. Although the filter and router caches
get *flushed* using a single register, they use distinct registers
(ENDP_FILTER_CACHE_CFG and ENDP_ROUTER_CACHE_CFG) for configuration.
And although there *exists* a FILT_ROUT_CACHE_CFG register, it is
not needed in upstream code. So get rid of definitions related to
FILT_ROUT_CACHE_CFG, because they are not needed.
Fixes: 8ba59716d16a ("net: ipa: define IPA v5.0+ registers")
