soc: mediatek: mtk-svs: Use bitfield access macros where possible
In order to enhance readability and safety during registers setup and value retrieval, redefine a few register related macros and convert all open-coded instances of bitfield setting/retrieval to use the FIELD_PREP() and FIELD_GET() macros. While at it, some macros were renamed to further enhance readability. This commit brings no functional changes.
