Subject: [PATCH] mac80211/rt2x00: sync Rt3352 support

The original patch was accepted into linux-next in a slightly modified form.
In order to provide integrity to follow-up patches, replace the patch in OpenWrt
with the (semantically identical) now upstream patch.
(commit 03839951515b0ea2b21d649b1fe7b63f9817d0c8 in wireless-testing)

+Subject: [PATCH] rt2x00: add MediaTek/RaLink Rt3352 WiSoC
+
+Support for the RT3352 WiSoC was developed for and tested with the ALL5002
+devboard running OpenWrt. For now, this supports only devices with internal
+TXALC. Corrections were made according to the remarks of Stanislaw Gruszka and
+Gertjan van Wingerde, thank you guys for reviewing!
