Updates the ServiceState cell bandwidths from PhysicalChannelConfig
indication. Uses the RatRatcheter to conditionally update the
ServiceState bandwidths iff the current PhysicalChannelConfigs have a
greater aggregate bandwidth than the current ServiceState bandwidths.
Ratchets the bandwidth list until cell change.
