Firmware advertises support for handling NSS ratio information as a part of service ready ext event using nss_ratio_enabled flag. Save this information in ath12k_pdev_cap to calculate NSS ratio. Additionally, reorder the code by moving ath12k_peer_assoc_h_phymode() before ath12k_peer_assoc_h_vht() to ensure that arg->peer_phymode correctly reflects the bandwidth in the max NSS calculation.

Fix this by utilizing nss_ratio_enabled and nss_ratio_info fields sent by firmware in service ready event. However, if firmware advertises EXT NSS BW support in VHT caps as 1(1x2) and when nss_ratio_info indicates 1:1, reset the EXT NSS BW Support in VHT caps to 0 which indicates 1x1. This is to avoid incorrectly choosing 1:2 NSS ratio when using the default VHT caps advertised by firmware.
