drm/amd/display: fix odm k2 div calculation
Correct setting is div by 2 for odm. Seamless odm transitions are enabled with enable_dp_dig_pixel_rate_div_policy debug flag. Fixes: a2c7356f526d ("drm/amd/display: fix pixel rate update sequence") Reviewed-by: Nicholas Kazlauskas <nicholas.kazlauskas@amd.com> Acked-by: Hamza Mahfooz <hamza.mahfooz@amd.com> Signed-off-by: Dmytro Laktyushkin <dmytro.laktyushkin@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
