ice: refactor RSS configuration

Browse Source 
Refactor the driver to use a communication data structure for RSS
config. To do so we introduce the new ice_rss_hash_cfg struct, and then
pass it as an argument to several functions.

Also introduce enum ice_rss_cfg_hdr_type to specify a more granular and
flexible RSS configuration:

ICE_RSS_OUTER_HEADERS - take outer layer as RSS input set
ICE_RSS_INNER_HEADERS - take inner layer as RSS input set
ICE_RSS_INNER_HEADERS_W_OUTER_IPV4 - take inner layer as RSS input set for
                                     packet with outer IPV4
ICE_RSS_INNER_HEADERS_W_OUTER_IPV6 - take inner layer as RSS input set for
                                     packet with outer IPV6
ICE_RSS_ANY_HEADERS - try with outer first then inner (same as the
		      behaviour without this change)

Finally, move the virtchnl_rss_algorithm enum to be with the other RSS
related structures in the virtchnl.h file.

There should be no functional change due to this patch.
