soc: qcom: geni-se: Add geni_icc_set_bw_ab() function

Add a new function geni_icc_set_bw_ab() that allows callers to set
average bandwidth values for all ICC (Interconnect) paths in a single
call. This function takes separate parameters for core, config, and DDR
average bandwidth values and applies them to the respective ICC paths.

This provides a more convenient API for drivers that need to configure
specific average bandwidth values.
