drm: meson: viu: use proper macros instead of magic constants

Browse Source 
This patch add new macros which are used to set the following
registers:
- VIU_SW_RESET
- VIU_OSD1_CTRL_STAT
- VIU_OSD2_CTRL_STAT
- VIU_OSD1_FIFO_CTRL_STAT
- VIU_OSD2_FIFO_CTRL_STAT
- VIU_MISC_CTRL0
- VIU_OSD_BLEND_CTRL
- OSD1_BLEND_SRC_CTRL
- OSD2_BLEND_SRC_CTRL
- DOLBY_PATH_CTRL
