Subject: [PATCH 4.14 301/496] net: dsa: mt7530: fix module autoloading for OF platform drivers

4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Sean Wang <sean.wang@...iatek.com>

[ Upstream commit 3c82b372a9f44aa224b8d5106ff6f1ad516fa8a8 ]

It's required to create a modules.alias via MODULE_DEVICE_TABLE helper
for the OF platform driver. Otherwise, module autoloading cannot work.
