The lightmaps look incorrect with artefacts and very bright when a scene with multiple lights and light probes is deployed to a mobile device platform.

Steps to reproduce:
1) Open the project attached to the case.
2) Open File > Build Settings and switch the platform to iOS or Android.
3) Deploy the build to the device.
4) Observe the bug.

Notes:
- Works as expected in 5.4.0f2 and 5.4.0f3
