qcacld-3.0: Add policy attribute to SPECTRAL_SCAN subcommands

According to new changes in kernel 5.4 version onwards, driver has to
provide the policy for a NL command to be verified against while
registering wiphy to the kernel.

To satisfy kernel 5.4 requirement add policy to following vendor
commands as part of this change:
	QCA_NL80211_VENDOR_SUBCMD_SPECTRAL_SCAN_START
	QCA_NL80211_VENDOR_SUBCMD_SPECTRAL_SCAN_STOP
	QCA_NL80211_VENDOR_SUBCMD_SPECTRAL_SCAN_GET_CONFIG

CRs-Fixed: 2634094
