Add MT7925_PCIE_MAC_{INT_ENABLE,PM} macros and mt7925_pcie_reg
struct. Update all PCIe register accesses in pci.c, pci_mac.c, and
pci_mcu.c to use dev->pcie_reg->{imask,pm}.
This is a preparation patch before enabling MT7928 PCIe support.

Replace shared MT_INT_RX_DONE_* macros with chip-specific
MT7925_INT_RX_DONE_{DATA,WM,WM2,ALL} and populate all_complete_mask
in mt7925_irq_map. Update resume and mac_reset paths accordingly.

MT7927 needs DBDC enabled and uses a fixed firmware band assignment for
2.4GHz and 5/6GHz BSS contexts.
Reprogram the STA dev context when the channel context is assigned so the
firmware sees the updated band_idx before the BSS is used. This avoids
stale band programming after band changes.

The mac_reset and resume paths use the hardcoded MT_INT_RX_DONE_ALL
constant (bits 0-2) to re-enable RX interrupts. This is correct for
MT7925 (RX rings 0, 1, 2) but wrong for chips using different ring
indices.
Define a per-chip irq_map with the correct RX interrupt enable bits and
replace hardcoded MT_INT_RX_DONE_ALL with irq_map field reads in the
resume and mac_reset paths. Add the MT7927 irq_map with interrupt bits
matching its RX ring layout (rings 4, 6, 7), selected at probe time
based on PCI device ID.
This ensures the correct interrupt bits are enabled regardless of the
chip variant.

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 does a lot of:
local_bh_disable();
napi_enable(...napi);
napi_schedule(...napi);
local_bh_enable();
local_bh_disable() is not a real lock, its most likely taken
because napi_schedule() requires that we invoke softirqs at
some point. napi_enable() needs to take a mutex, so move it
from under the BH protection.

We are introducing a new structure, mt792x_link_sta, to manage per-link
configurations in preparation for future station (STA) support of
Multi-Link Operation (MLO).
This patch only includes structural changes and does not involve any
logic changes.
We have moved relevant parameters, such as the wcid from the mt76_wcid
structure, from the mt7921x_sta structure to the mt792x_link_sta structure.
For current drivers that do not support MLO, there is only one link STA,
and link information is accessed via the deflink member.
However, we have not yet created the per-link BSS configuration indexed
by link ID for Multi-Link Device (MLD) support in mt7921x_sta.
This step needs to be completed before adding MLD support for STA mode.

Add mt7925, a new mac80211 driver for the MediaTek Wi-Fi 7 (802.11be) device
Filogic 360, which can support Station, AP, P2P, and monitor modes.
Filogic 360 supports max 4096-QAM/160MHz radio operation at 6 GHz, 5 GHz,
or 2.4 GHz with 2x2 antennas. This chip supports PCIe and USB bus type.
mt7925 supports Wi-Fi 6E and EHT rate with single link only at this moment,
whereas Wi-Fi 7 and its specific features are working in progress. They will be
introduced in further patches.
The driver is build tested by Intel's kernel test robot with both GCC and Clang
with several architecture. Sparse reports no warnings.
There are multiple authors, they are listed in alphabetical order below.
