Fixed a DEQP bug on DG2

For RGB565D0S0MS0,some pixels will be cleared incorrectly, when using the REP16 instruction on the DG2 platform to accelerate slow clear. Ref link: https://hsdes.intel.com/appstore/article-one/article/14017880152. For example, with glClear(0.125, 0.25, 0.5, 1), the corresponding pixel values are (32, 64, 128). When using the REP16 instruction on the DG2 platform to accelerate slow clear, some pixels will be cleared to (24, 60, 120). Tracked-On: OAM-123699 Signed-off-by: Li,Gaoshun [email protected]
