MGS-6664-4 [#imx-2955] Fix OpenCL regression issue

Since memory for sg_table doesn't have 4G limit, need to remove
__GFP_DMA32 from normal_gfp when calling sg_alloc_table_from_pages,
which causes error info "Unexpected gfp: 0x4 (GFP_DMA32). Fixing up to
gfp: 0x12220 (__GFP_HIGH|__GFP_ATOMIC|__GFP_NOWARN|__GFP_NORETRY).
Fix your code!" when doing test_integer_ops.
