    mac80211: remove ath10k delayed initialization hack
    
    LEDE no longer requires all PHYs to be initialized to
    create the configuration files during bootup. This patch
    removes the now obsolete ath10k patch.

-Subject: [PATCH] ath10k: Don't initialize devices asynchronously
-
-OpenWrt requires all PHYs to be initialized to create the configuration files
-during bootup. ath10k violates this because it delays the creation of the PHY
-to a not well defined point in the future.
-
-Forcing the work to be done immediately works around this problem but may also
-delay the boot when firmware images cannot be found.
