Some platform vendors need to apply their own regualtory settings and the
vendor-specific data would be written in dts or acpi. This patch set adds
the functionalities to handle this per-device 5.9/6GHz channel
configurations.

2.18.0
From: Ming Yen Hsieh <[email protected]>
The clc event can report the radio configuration for the corresponding
country and the driver would take it as regulatory information of a
certain platform device.
This patch would change the clc commnad from no-waiting to waiting for
event. For backward compatible, we also add a new nic capability tag
to indicate the firmware did support this new clc event from now on.

The 5.9/6GHz channel license of a certain platform device has been
regulated in various countries. That may be difference with standard
Liunx regulatory domain settings. In this case, when .reg_notifier()
called for regulatory change, mt792x chipset should update the channel
usage based on clc or dts configurations.
Channel would be disabled by following cases.
* clc report the particular UNII-x is disabled.
* dts enabled and the channel is not configured.
