	drm/tidss: dispc: Get rid of FLD_VAL
The FLD_VAL function is an equivalent to what FIELD_PREP + GENMASK provide, so let's drop it and switch to the latter. Signed-off-by: Maxime Ripard <mripard@kernel.org> Link: https://lore.kernel.org/r/20250827-drm-tidss-field-api-v3-4-7689b664cc63@kernel.org Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ideasonboard.com>
