MA-21513 [#imx-3206] Fix AXI BUS ERROR on more than 4G DDR board.
Meet GPU dump when run the below case on more than 4G DDR board.
CtsNNAPITestCases TestRandomGraph/RandomGraphTest#LargeGraph_TENSOR_FLOAT16_Rank*
The above 4G address can be rejected when doing _UserMemoryAttach.
But will be used by _UserMemoryPhysical as os->paddingPage is allocated
with __GFP_HIGHMEM.
Here change __GFP_HIGHMEM to __GFP_DMA32 to avoid the GPU dump.
