Add MT7902 PCIe specific DMA layout overrides for MCU TXQ index, RX ring
size, and MCU_WA usage. Common layout remains the default for other chips.
This is a prerequisite patch before enabling MT7902 PCIe support.

MediaTek has asked to switch from the ISC license to BSD-3-Clause-Clear,
in order to improve clarity and the legal integrity of the code.
The BSD-3-Clause license includes the "no endorsement" clause, which is
important for protecting the reputation of the original authors and
contributors by preventing unauthorized use of their names for endorsement
purposes.
This clause is absent in the BSD-2-Clause license, which is more permissive
but lacks this specific protection.
This change also cleans up the license of some Kconfig/Makefile files,
which were accidentally marked as GPL.
The GPL 2.0 remains in use on mt76x0, as well as two source files in mt7615
for which the license situation still needs to be clarified.

Any station configured with an AID over 20 causes a firmware crash.
This situation occurred in our testing using an AP interface on 7922
hardware, with a modified hostapd, sourced from Mediatek's OpenWRT
feeds.
In stock hostapd, station AIDs begin counting at 1, and this
configuration is prevented with an upper limit on associated stations.
However, the modified hostapd began allocation at 65, which caused the
firmware to crash. This fix does not allow these AIDs to work, but will
prevent the firmware crash.
This crash was only seen on IFTYPE_AP interfaces, and the fix does not
appear to have an effect on IFTYPE_STATION behavior.

In multi-channel scenarios, the granted channel must be aborted before
suspending. Otherwise, the firmware will be put into a wrong state,
resulting in an association failure after resuming.

if necessary.

When enter suspend/resume while in a connected state, the upper layer
will trigger disconnection before entering suspend, and at the same time,
it will trigger regd_notifier() and update CLC, causing the CLC event to
not be received due to suspend, resulting in a command timeout.
Therefore, the update of CLC is postponed until resume, to ensure data
consistency and avoid the occurrence of command timeout.

We actually don't need the reserve the 512 entries for the MCU firmware

phase to save the most of space and the reduction can significantly help

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.
