iwlagn: new RXON processing for modern devices
In order to simplify the flow, and make new enhancements easier, separate out the RXON processing for modern AGN (5000 and newer) from RXON processing for the older 3945 and 4965 devices. Avoid changing these old ones to avoid regressions and move their code to a new file (iwl-legacy.c). 4965 gets the commit_rxon that used to be common for all AGN devices, but with removed PAN support. The new RXON processing is more central and does more work in committing, so that it is easier to follow. To make it more evident what is split out for legacy, split the necessary operations for that into a new struct iwl_legacy_ops. Those parts that still exist in the new AGN code don't need to be parametrized.
