New upcoming chip is RTL8852BE-VT (or RTL8852BTE; 8852BT PCIE interface),
which is a variant of 8852B, and many codes excepting to RF calibration
can be shared, so move common code to an new kernel module named
rtw89_8852b_common.ko.
No logic change.

Add 8922AE to Makefile and Kconfig. Currently, it can support STA, AP and
monitor modes with good performance. Implemented initial BT-coexistence
function only, and will to fine tune this component.

Since 8851BE is ready, so add 8851BE to Makefile and Kconfig. Currently,
it can support STA, AP and monitor modes with good performance.

Now, basic materials for 8852be are ready, so add 8852be to Kconfig and
Makefile. Current version can support STA, AP and monitor modes.
We still fine tune some features, such as BT coexistence, performance, and
power consumption.

This initial vesion is usable now. It can support STA, AP and monitor
modes, so we can add 8852ce to Kconfig and Makefile.
We are still working on some features, such as deep power save, and BT
coexistence. But, this version still can have a good WiFi-only performance
already, and will continue to fine tune power consumption.

We are planning to support more chipsets, e.g. 8852C. Before that, we
consider architecutre to handle multiple kinds of chipsets. Obviosuly,
based on original design, rtw89_core module will have large size even
if there is only one chipset under running. It is because all chipset
related things are put in rtw89_core now. To reduce such overhead, we
extract modules of rtw89 and adjust dependencies between modules.
The following assumes that 8852AE, 8852AU, and 8852CE are all supported,
we describe the difference before and after extraction.
[Before extraction]
-------------
|------------------------------------ | rtw89_usb |
V -------------
--------------------------------------- -------------
| rtw89_core (including 8852A, 8852C) | <--- | rtw89_pci |
--------------------------------------- -------------
The data of 8852A and 8852C are built in rtw89_core.
And rtw89_pci is the entry of 8852AE and 8852CE.
And rtw89_usb is the entry of 8852AU.
[After extraction]
------------- ----------------
|----------- | rtw89_usb | <-------- | rtw89_8852au |
| ------------- ----------------
V --------------- |
-------------- | | <---------------
| rtw89_core | <--- | rtw89_8852a |
-------------- | | <---------------
^ ^ --------------- |
| | ------------- ----------------
| | | | <-------- | rtw89_8852ae |
| |----------- | rtw89_pci | ----------------
| | | <-----------------
| ------------- |
| --------------- ----------------
|--------------- | rtw89_8852c | <------ | rtw89_8852ce |
--------------- ----------------
The data of 8852A/8852C is extracted to rtw89_8852a/rtw89_8852c.
And rtw89_pci/rtw89_usb handles only common flow of pci/usb bus.
Finally, 8852AE, 8852AU, and 8852CE have individual entry modules,
i.e. rtw89_8852ae, rtw89_8852au, and rtw89_8852ce correspondingly.

This driver named rtw89, which is the next generation of rtw88, supports
Realtek 8852AE 802.11ax 2x2 chip whose new features are OFDMA, DBCC,
Spatial reuse, TWT and BSS coloring; now some of them aren't implemented
though.
The chip architecture is entirely different from the chips supported by
rtw88 like RTL8822CE 802.11ac chip. First of all, register address ranges
are totally redefined, so it's impossible to reuse register definition. To
communicate with firmware, new H2C/C2H format is proposed. In order to have
better utilization, TX DMA flow is changed to two stages DMA. To provide
rich RX status information, additional RX PPDU packets are added.
Since there are so many differences mentioned above, we decide to propose
a new driver. It has many authors, they are listed in alphabetic order:
