drm/amd/display: Update MCIF_ADDR macro to address IGT DWB regression
[Why] A previous warning-fix commit updated type casts in the DCN3 mmhubbub code but missed updating the MCIF_ADDR macro to the correct, fully parenthesized and casted version. This caused a regression during DWB tests, where address values could be misinterpreted, potentially leading to incorrect hardware programming. [How] Updated the MCIF_ADDR macro in dcn30_mmhubbub.c to use the proper parenthesization and type casting, ensuring correct address handling. Removed redundant casts from REG_UPDATE calls for improved clarity and consistency with current coding standards.
