Comment(by dsd):

 I attached a debug log. I've only had time to investigate the suspend part
 so far. mwifiex_sdio_suspend calls mwifiex_enable_hs() and this is where
 the 8-ish seconds are spent delaying the whole suspend routine. It looks
 like it might be completing the scan before executing the host sleep
 command. IIRC, in the libertas case, the host sleep command was expedited
 to the front of the queue. There is no need to continue this scanning
 before going into suspend.
