qcacmn: Configure TWT AP pdev count for QCA6490

QCA6490 expects twt_ap_pdev_count 2, to bring up twt sap on 2g.
Currently twt_ap_pdev_count is derived from num of radios and is
1 in case of MCC.
Configure twt_ap_pdev_count value equal to number of phy
advertised by firmware in wmi service ready ext event, configure
under flag WLAN_TWT_AP_PDEV_COUNT_NUM_PHY if defined in kbuild
