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.

mt76_eeprom_override has of_get_mac_address, which can return
-EPROBE_DEFER if the nvmem driver gets loaded after mt76 for some
reason.
Make sure this gets passed to probe so that nvmem mac overrides always

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.

The firmware can have the capability to manage the channel context
scheduling on multiple roles running on the device including Station,
AP and P2P GC/GO mode (will be extended based on the future patchset)
to help users sharing the network with others on a single device.
The firmware is able to support the channel chanctx up to 2 interface
simultaneously running on the different channels.
Another thing to be noted is that before the driver is going sent out the
management frames, the driver has to get the privilege from the firmware
to occupy the current channel context until the frame handshake is
completed and then get the privilege back to the firmware.
