The mtcl table, configured by platform vendor, provides regulatory
information for 5.9/6 GHz channels. mt792x should work on
corresponding channels supported by mtcl. This patch would parse
the settings in mtcl table and apply the result into chip side.

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.

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.

would be better to put the code in chip folder. And we can provide
more chip capability information in mt792x_phy without making
mt76_phy much bigger.
The three functions would be moved to mt7921 folder and renamed.

In the Xiaomi Redmibook 15 Pro (2023) laptop I have got, a wifi chip is
used, which according to its PCI Vendor ID is from "ITTIM Technology".
This chip works flawlessly with the mt7921e module. The driver doesn't
bind to this PCI device, because the Vendor ID from "ITTIM Technology" is
not recognized.
This patch adds the PCI Vendor ID from "ITTIM Technology" to the list of
PCI Vendor IDs and lets the mt7921e driver bind to the mentioned wifi
chip.

For some cases as below, we may encounter the unpreditable chip stats
in driver probe()
* The system reboot flow do not work properly, such as kernel oops while
rebooting, and then the driver do not go back to default status at
this moment.
* Similar to the flow above. If the device was enabled in BIOS or UEFI,
the system may switch to Linux without driver fully shutdown.
To avoid the problem, force push the device back to default in probe()
* mt7921e_mcu_fw_pmctrl() : return control privilege to chip side.
* mt7921_wfsys_reset() : cleanup chip config before resource init.
