iwlwifi: mvm: support rss queues configuration command
9000 series supports multi-queue rx. The hardware needs
to be configured with the hash functions to perform and
indirection table that maps hash results to the relevant
CPUs\queues.
Support this configuration.
Add debugfs hook to configure the indirection table in
order to enable performance analysis. The configuration
is stateless, receives a partial or full pattern and sends
the command to the firmware.
