Subject: [PATCH 4.19 053/206] gpio: dwapb: Append MODULE_ALIAS for platform driver

From: Andy Shevchenko <andriy.shevchenko@...ux.intel.com>

[ 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.

Fixes: 3d2613c4289f ("GPIO: gpio-dwapb: Enable platform driver binding to MFD driver")
