VOP pitch register is word align, need align to word.
VOP_WIN0_VIR:
bit[31:16] win0_vir_stride_uv
Number of words of Win0 uv Virtual width
bit[15:0] win0_vir_width
Number of words of Win0 yrgb Virtual width
ARGB888 : win0_vir_width
RGB888 : (win0_vir_width*3/4) + (win0_vir_width%3)
RGB565 : ceil(win0_vir_width/2)
YUV : ceil(win0_vir_width/4)
