drm: meson: vpp: use proper macros instead of magic constants
This patch add new macros which are used to set the following registers: - VPP_OSD_SCALE_COEF_IDX - VPP_DOLBY_CTRL - VPP_OFIFO_SIZE - VPP_HOLD_LINES - VPP_SC_MISC - VPP_VADJ_CTRL Signed-off-by: Julien Masson <jmasson@baylibre.com> Reviewed-by: Neil Armstrong <narmstrong@baylibre.com> [narmstrong: put back 0x1020080 in VPP_DUMMY_DATA1 for GXM] Signed-off-by: Neil Armstrong <narmstrong@baylibre.com> Link: https://patchwork.freedesktop.org/patch/msgid/86tvcf82eu.fsf@baylibre.com
