drm/msm: register a fault handler for display mmu faults

Browse source

In preparation to register a iommu fault handler for display
related modules, register a fault handler for the backing
mmu object of msm_kms.

Currently, the fault handler only captures the display snapshot
but we can expand this later if more information needs to be
added to debug display mmu faults.
