[PATCH 5/6] clk: mediatek: Reserve missing MT8196 MDP clock IDs

[Akari Tsuyukusa]

Reserve the binding-defined CLK_MDP_SMI0_SMI and
CLK_MDP1_SMI0_SMI IDs with dummy clocks in the MT8196 MDP
clock providers.

These clocks are not implemented by the current MDP clock
driver and have no known consumers. Keeping the slots occupied
preserves the binding-defined ID space and prevents out-of-bounds
accesses in the descriptor-based onecell data.
