Dave Ertman c24a65b6a2 iidc/ice/irdma: Update IDC to support multiple consumers
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.
