net: marvell: prestera: devlink: add traps with DROP action
Add traps that have init_action being set to DROP.
Add 'trap_drop_counter_get' (devlink API) callback implementation,
that is used to get number of packets that have been dropped by the HW
(traps with action 'DROP').
Add new FW command CPU_CODE_COUNTERS_GET.
