drm/msm/dpu: don't allow overriding data from catalog
The data from catalog is marked as const, so it is a part of the RO
segment. Allowing userspace to write to it through debugfs can cause
protection faults. Set debugfs file mode to read-only for debug entries
corresponding to perf_cfg coming from catalog.
