soc: qcom: geni-se: Refactor geni_icc_get() and make qup-memory ICC path optional
The "qup-memory" interconnect path is optional and may not be defined
in all device trees. Unroll the loop-based ICC path initialization to
allow specific error handling for each path type.
The "qup-core" and "qup-config" paths remain mandatory and will fail
probe if missing, while "qup-memory" is now handled as optional and
skipped when not present in the device tree.
