5f93676830 wifi: rtw88: enable TX reports for the management queue 
This is needed for AP mode. Otherwise client sees the network, but
can't connect to it.

REG_FWHW_TXQ_CTRL+1 is set to WLAN_TXQ_RPT_EN (0x1F) in common mac
init function (__rtw8723x_mac_init), but the value was overwritten
from mac table later.

Tables with register values for phy parameters initialization are
copied from vendor driver usually. When table will be regenerated,
manual modifications to it may be lost. To avoid regressions in this
case new callback mac_postinit is introduced, that is called after
parameters from table are set.

Tested on rtl8723cs, that reuses rtw8703b driver.

57d6be36cf wifi: rtw88: Rename the RTW_WCPU_11{AC,N} enums 
The RTW_WCPU_11AC and RTW_WCPU_11N enums are used to identify two
types of microcontrollers used in Realtek chips, but these names are
misleading. The "11AC" type was also used in 11n devices (e.g.
RTL8733BU, not supported by rtw88), and the "11N" type was also used
in 11ac devices (RTL8821AU, RTL8812AU).

Rename RTW_WCPU_11AC to RTW_WCPU_3081 and RTW_WCPU_11N to RTW_WCPU_8051.
(8051 is well known. It's less clear what 3081 is, but the out of tree
drivers use this name.)

b8d49bb8d1 wifi: rtw88: Don't set SUPPORTS_AMSDU_IN_AMPDU for RTL8814AU 
RTL8814AU doesn't work well with SUPPORTS_AMSDU_IN_AMPDU. The RX speed
is noticeably lower and the VHT RX statistics are strange. Typical
values with SUPPORTS_AMSDU_IN_AMPDU:

[Rx Counter]:
 * CCA (CCK, OFDM, Total) = (0, 2455, 2455)
 * False Alarm (CCK, OFDM, Total) = (0, 69, 69)
 * CCK cnt (ok, err) = (0, 0)
 * OFDM cnt (ok, err) = (1239, 2)
 * HT cnt (ok, err) = (0, 0)
 * VHT cnt (ok, err) = (21, 12109)

The "VHT ok" number is not believable.

And without SUPPORTS_AMSDU_IN_AMPDU:

Add a new member "amsdu_in_ampdu" in struct rtw_chip_info and use it
to set SUPPORTS_AMSDU_IN_AMPDU only for the other chips.

0d2a88690e wifi: rtw88: Set AMPDU factor to hardware for RTL8814A 
Tell the chip the maximum AMPDU size supported by the AP. This greatly
improves the TX speed of RTL8814AU in the 2.4 GHz band. Before: ~90
Mbps. After: ~300 Mbps.
