dolby: Graphics blending tests fail when 4k output [4/4]

PD#SWPL-10128

Problem:
Osd scaling algorithm has bad effect

Solution:
Add repeat mode
echo 0 > /sys/module/fb/parameters/osd_auto_adjust_filter
echo 9 > /sys/module/fb/parameters/osd_h_filter_mode
echo 9 > /sys/module/fb/parameters/osd_v_filter_mode

Verify:
Verified on sm1
