mt76_register_debugfs_fops() returns the dentry from
debugfs_create_dir(), which yields an error pointer on failure
(notably ERR_PTR(-ENODEV) when CONFIG_DEBUG_FS=n), never NULL. Per
commit ff9fb72bc077 ("debugfs: return error values, not NULL"),
callers do not need to check the return value.
Drop the dead !dir checks in mt7615/mt7915/mt7921/mt7925/mt7996
_init_debugfs(). Converting them to IS_ERR() instead would have
exposed a probe abort on CONFIG_DEBUG_FS=n, since each
*_init_debugfs() caller propagates the helper's return value.
This patch supersedes an earlier proposal that converted the checks
to IS_ERR().

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.

After commit 'd430dffbe9dd ("mt76: mt7921: fix a possible race
enabling/disabling runtime-pm")', runtime-pm is always disabled in the
fw even if the user requests to enable it toggling debugfs node since
mt7921_pm_interface_iter routine will use pm->enable to configure the fw.
Fix the issue moving enable variable configuration before running
mt7921_pm_interface_iter routine.
