This patch adds the attributes, policy and parsing code to allow userland
to send the info about the BSS coloring settings to the kernel. We also
enable strict policy parsing.

It is now possible to propagate BSS color settings into the subsystem. Lets
make mac80211 also handle them so that we can send them further down the
stack into the drivers. We drop the old bss_color field and change iwlwifi
to use the new he_bss_color struct.

If the he_operation field of the beacon sets a BSS color, we need to inform
the FW of the settings. This patch adds the WMI command handlers required
to do so.

This patch adds code to handle the BSS_CHANGED_BSS_COLOR flag. It will
trigger the propagation of BSS color settings into the FW. Handling is
slightly different between AP and STA interfaces.

There were trivial conflicts in wmi.h and some checkpatch warnings, fixed those
in the pending branch.
