drm/amd/display: Limit array index according to architecture

[WHY & HOW]
ctx->architecture determine array sizes of ODMMode and DPPPerSurface
arrays to __DML2_WRAPPER_MAX_STREAMS_PLANES__ or __DML_NUM_PLANES__,
and these array index should be checked before used

This fixes 2 OVERRUN issues reported by Coverity.
