fix: llc: ocp, pcac: temporarily force disable of LLC
Force disable of LLC for A8k-OCP and A7k-PCAC boards, regardless
of LLC_DISABLE compilation flag.
This is due to an issue observed while running iperf with
smartNIC End Poind driver/application, while LLC is enabled.
As a temporary workaround, until issue is solved, we disable LLC.
