interconnect: qcom: Ensure that the floor bandwidth value is enforced 

Take into account the initial bandwidth from the framework and update
the internal sum and max values before committing if needed. This will
ensure that the floor bandwidth values are enforced until the providers
get into sync state.

Fixes: 7d3b0b0d81 ("interconnect: qcom: Use icc_sync_state")
