In preparation of supporting more than a single core PCI driver for RDMA, move ice specific structs like qset_params, qos_info and qos_params from iidc_rdma.h to iidc_rdma_ice.h. Previously, the ice driver was just exporting its entire PF struct to the auxiliary driver, but since each core driver will have its own different PF struct, implement a universal struct that all core drivers can provide to the auxiliary driver through the probe call.
