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.
