Add phantom slice support on IVB+
HW requires driver to add a phantom slice when FirstMbX and FirstMbY are
not 0, in order to avc decoding error concealment. Otherwise, GPU may hang.
This patch is a workround for bug: https://bugs.freedesktop.org/show_bug.cgi?id=81447
v1->v2: Follow haihao's suggestion to use common funcion of gen6 phantom slice.
v2->v3: Remove an extraneous newline.
