[ALPS08866253] JPEG Enc occur translation fault



[Description]
For YUYV format,HW image stride is round_up(width*2,32),
but driver set stride is width*2,lead to HW input size
mismatch with driver input size,HW access
address out of bounds.

[Test]
Build and Test ltp_jpegenc and Camera take pictures pass
