mac80211: enable ath10k LED support by default

Commit 61d57a2f88 adds ath10k LED
support, but doesn't add an option to actually enable it.

After enabling this option, a LED named ath10k-phy0 appears in sysfs,
and a trigger can be assigned to it. Since 60deb3cdef the default set
trigger is the tpt one.

Enable it by default, as most devices using ath10k chips shouldn't be
severely space-constrained. There are likely many devices that can
benefit from having it enabled, like my testing device.

After:

 245979    8899      16  254894   3e3ae ath10k_core.ko

Tested on a D-Link DAP-2695-A1 (ar71xx).
