In outdoor deployment, when the target sends STOP_TX event, the 6 GHz
AP continues to beacon in the SP power mode, without bringing down the VAP.
In mlme_check_curchan_and_set_ap_pwr_type, since the
afc_power_event_received flag is cleared and set to false during STOP_TX,
the API wlan_reg_get_best_pwr_mode returns LPI as the best power mode.
When LPI is given as input to wlan_reg_set_ap_pwr_and_update_chan_list,
it returns an error as LPI rules are absent in the pdev
(outdoor deployment). But the error status is not handled. Current channel
list also is not updated with the AFC_NOT_FLAG. When the channel list is
sent to the hostapd, NO_IR flag is set based on the presence of the
AFC_NOT_DONE flag in the current channel list. As a result NO_IR flag is
not sent to the hostapd, and the VAP remains in the up state.
To fix this issue, in reg_get_best_pwr_mode_from_eirp_list, skip the
unsupported modes (in this case LPI and VLP), from best power mode
computation. Also, in reg_get_sp_eirp, return the SP EIRP when no rules
other than SP are available.
Also, rename reg_get_eirp_for_non_sp to reg_get_eirp_from_mas_chan_list.
Modify reg_get_sp_eirp to call reg_get_eirp_from_mas_chan_list when
CONFIG_AFC_SUPPORT is not defined.
