qcacld-3.0: Add policy attribute for ll_stats_clr

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 accommodate these changes, add policy for the following
vendor command that is being registered in the driver
	QCA_NL80211_VENDOR_SUBCMD_LL_STATS_CLR
