ENGR00321142 gis: faster auto standards detection

Vadc need time to auto standards detection,
the default standard is NTSC, if vadc connect to PAL
camera and no enough time to detect the video mode,
driver will get NTSC mode.

Confirmation from chip design architecture auto detect function
is not required by rear-view camera application.

Setting register vdec_stddbg standard_filte bits to 0
makes the standard detection faster, the issue duplicate
decrease to 1%.
