drm/amd/display: Add instance field to struct mpc
[Why]
struct mpc has no instance identifier, unlike other DC hardware
blocks. Debug and tracing helpers need one to identify the block.
[How]
Add an inst member to struct mpc and initialize it to 0 in every
dcnXX_mpc_construct(), since there is one MPC instance per ASIC.
