qcacmn: Add QCA vendor commands for spectral scan

Add following vendor commands and their handlers.

 1) QCA_NL80211_VENDOR_SUBCMD_SPECTRAL_SCAN_START
        Set the spectral parameters and start scan.
 2) QCA_NL80211_VENDOR_SUBCMD_SPECTRAL_SCAN_GET_STATUS
        Stop spectral scan.
 3) QCA_NL80211_VENDOR_SUBCMD_SPECTRAL_SCAN_GET_CONFIG
        Get current values of spectral parameters.
 4) QCA_NL80211_VENDOR_SUBCMD_SPECTRAL_SCAN_GET_DIAG_STATS
        Get stats for spectral scan debug.
 5) QCA_NL80211_VENDOR_SUBCMD_SPECTRAL_SCAN_GET_CAP_INFO
        Get the spectral hardware capability.
 6) QCA_NL80211_VENDOR_SUBCMD_SPECTRAL_SCAN_GET_STATUS
        Get the current status of spectral scan.
