amlv4l2dec: CB2 set min width/height to 16 [1/1]

PD#SWPL-181681

Problem:
test YTS 144P case failure. because dw is
VDEC_DW_AFBC_x2_1_4_DW,decoder output video height
is 36 pixel. the min height of src caps is 64. it
causes caps negotiated failure.

Solution:
set nv12,nv21,nm12,nm21 min to 16

Verify:
