Add QCA vendor interface to get SAR capabilities to userspace

Browse source 
Add QCA_NL80211_VENDOR_SUBCMD_GET_SAR_CAPABILITY to get various SAR
capabilities supported by the WLAN firmware to userspace. These
capabilites are usually reported by the firmware during the initial
bootup handshake with the driver. Based on these capabilities, user
space can choose proper SAR indexes.
