drm/amd/display: Remove redundant i2c structs [Why] The i2c code contains two structs that contain the same information as i2c_payload [How] Replace references to those structs with references to i2c_payload dce_i2c_transaction_request->status was written to but never read, so all references to it are removed Signed-off-by: David Francis <David.Francis@amd.com> Reviewed-by: Jordan Lazare <Jordan.Lazare@amd.com> Acked-by: Leo Li <sunpeng.li@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

drm/amd/display: Create new i2c resource [Why] I2C code did not match dc resource model and was generally unpleasant [How] Move code into new svelte dce_i2c files, replacing various i2c objects with two structs: dce_i2c_sw and dce_i2c_hw. Fully split sw and hw code paths. Remove all redundant declarations. Use address lists to distinguish between versions. Change dce80 code to newer register access macros.
