Add QCA vendor interface to fetch thermal statistics from the driver

Browse source 
Enhance QCA_NL80211_VENDOR_SUBCMD_THERMAL_CMD to fetch thermal
statistics for different temperature levels from the driver to
userspace. The statistics will be stored in the driver/firmware for
predefined temperature levels and will be reported to userspace when
QCA_NL80211_VENDOR_SUBCMD_THERMAL_CMD is sent with the command type
QCA_WLAN_VENDOR_ATTR_THERMAL_CMD_TYPE_GET_THERMAL_STATS.

The thermal statistics can be cleared from userspace by sending a
QCA_NL80211_VENDOR_SUBCMD_THERMAL_CMD command with the type
QCA_WLAN_VENDOR_ATTR_THERMAL_CMD_TYPE_CLEAR_THERMAL_STATS.
