deinterlace: add pulldown info to vframe. [1/2]

PD#SWPL-11389

Problem:
PQ need work around for 1080i(based on VLSI's suggestions)
co-work with yanling/mingliang

Solution:
add pulldown information to vframe;
u32 di_pulldown:
-bit 3: interlace
-bit 2: flmxx
-bit 1: flm22
-bit 0: flm32

Verify:
TL1
