iwlwifi: mvm: Define AUX ROC Command 



Add new AUX ROC command that is intended for HS2.0 purposes.
It is used to send ANQP requests on a specific channel.

This command requests the firmware to trigger a time event
and remain on a certain channel for a given duration.
Triggering the time event is done by using the Aux
Framework in the firmware, and makes use of the Aux station
(similarly to scan).

 * Aux ROC command

 *

 * Command requests the firmware to create a time event for a certain duration

 * and remain on the given channel. This is done by using the Aux framework in

 * the FW.

 * The command was first used for Hot Spot issues - but can be used regardless

 * to Hot Spot.

 *

 * ( HOT_SPOT_CMD 0x53 )

 *

 * @id_and_color: ID and color of the MAC

 * @action: action to perform, one of FW_CTXT_ACTION_*

 * @event_unique_id: If the action FW_CTXT_ACTION_REMOVE then the

 *	event_unique_id should be the id of the time event assigned by ucode.

 *	Otherwise ignore the event_unique_id.

 * @sta_id_and_color: station id and color, resumed during "Remain On Channel"

 *	activity.

 * @channel_info: channel info

 * @node_addr: Our MAC Address

 * @reserved: reserved for alignment

 * @apply_time: GP2 value to start (should always be the current GP2 value)

 * @apply_time_max_delay: Maximum apply time delay value in TU. Defines max

 *	time by which start of the event is allowed to be postponed.

 * @duration: event duration in TU To calculate event duration:

 *	timeEventDuration = min(duration, remainingQuota)
