MLK-17311-1 gpu: imx: dpu: common: Set SC_C_KACHUNK_CNT as 32

The SC_C_KACHUNK_CNT is for dpu blit and represents
how many cycle counts is need to trigger DPR after
DPU shadow being loaded. The initial value is 0x20,
and will change to 0 after the first frame if not set.
So it need be set with a value greater than 0x20.
