tests/kms_plane_alpha_blend: Align width to 256B
Some display resolutions like 1366x768 6bpc which does not
have 64B aligned width are creating crc mismatch in
kms_plane_alpha_blend test on Intel platforms.
Also having different alignment requirement by different drivers,
256B aligned width should work for all drm drivers.
amdgpu and radeon, amdgpu_align_pitch: 256B
armada, armada_pitch: 128B
exynos_drm_gem_dumb_create: No alignment required
drm_gem_shmem_dumb_create: 8B
drm_gem_vram_fill_create_dumb: 8B
Thus 256B covers everything we see in the kernel drm drivers.
