Sometimes PCIe Advanced Error Reporting(AER), like bad TLP or
Data link protocol error, happens due to unstable pci signal or
no response from PCI host.

The rtw88 module names all start with the "rtw88_" prefix, but the
messages in dmesg mostly use the "rtw_" prefix. The messages from
rtw88_8723cs don't even have the underscore.
Use the KBUILD_MODNAME macro in every driver. This ensures that the
messages in dmesg will always use the module name.

Sparse lists the following for rtw88:
CHECK drivers/net/wireless/realtek/rtw88/rtw8822b.c
drivers/net/wireless/realtek/rtw88/rtw8822b.c:2500:22: warning: symbol 'rtw8822b_hw_spec' was not declared. Should it be static?
The warning arises because the external declaration for rtw8822b_hw_spec
occurs in rtw8822be.h, which is not included in rtw8822b.h. That line is
moved, and the now empty file rtw8822be.h is deleted.
Symbol 'rtw8822b_hw_spec' can be made constant.

Also strip out other duplicates from driver specific headers.
Ensure 'main.h' is explicitly included in 'pci.h' since the latter
uses some defines from the former. It avoids issues like:
from drivers/net/wireless/realtek/rtw88/rtw8822be.c:5:
drivers/net/wireless/realtek/rtw88/pci.h:209:28: error: ‘RTK_MAX_TX_QUEUE_NUM’ undeclared here (not in a function); did you mean ‘RTK_MAX_RX_DESC_NUM’?
209 | DECLARE_BITMAP(tx_queued, RTK_MAX_TX_QUEUE_NUM);
| ^~~~~~~~~~~~~~~~~~~~
Fixes the following W=1 kernel build warning(s):
drivers/net/wireless/realtek/rtw88/pci.c:1488:5: warning: no previous prototype for ‘rtw_pci_probe’ [-Wmissing-prototypes]
1488 | int rtw_pci_probe(struct pci_dev *pdev,

Make objects about 8822b functions and 8822b tables,
i.e. rtw8822b.o and rtw8822b_table.o, an individual
kernel module called rtw88_8822b.ko.
For 8822b pcie chip, i.e. 8822BE chip, add a chip
entry point module called rtw88_8822be.ko which
will depend on rtw88_8822b.ko and rtwpci.ko.
