wil6210: firmware download
Firmware download implemented but is still experimental feature; flag controlling it added, no_fw_load. It is true by default, use no_fw_load=N to activate feature. Reset flows also got some adjustment for the fw download to work Signed-off-by: Vladimir Kondratiev <qca_vkondrat@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
