MPV EGL patch
From 93a400edcabee9de0d6b464e081aa9c562085559 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Use eglGetPlatformDisplay when possible
And then fallback on eglGetDisplay if the initialization fails...
That said, currently the code only handle eglGetPlatformDisplay
with GBMm in order to initialize displays with DRM/KMS backends.
