[ Upstream commit c58220cba2e03618659fa7d5dfae31f5ad4ae9d0 ]
The commit 3d2613c4289f
("GPIO: gpio-dwapb: Enable platform driver binding to MFD driver")
introduced a use of the platform driver but missed to add the following line
to it:
MODULE_ALIAS("platform:gpio-dwapb");
Add this to get driver loaded automatically if platform device is registered.
