wil6210: temperature measurement
Firmware got support for temperature measurement. There are 2 temperature sensors: MAC and radio "not available" temperature - reported by FW as 0 or ~0 Signed-off-by: Vladimir Kondratiev <qca_vkondrat@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
