[RFC 9/9] wl12xx_sdio: declare support for NL80211_WOW_TRIGGER_ANYTHING trigger

[Eliad Peller <eliad@wizery.com>]

Finally, declare support for NL80211_WOW_TRIGGER_ANYTHING.

Since this feature requires the ability to stay awake while the host
is suspended, the support should be declared per-interface (sdio
will support it if it supports the MMC_PM_KEEP_POWER capability)
