185f7978bf Add IOMMU GFP_DMA32 patch for RK3568 8GB systems 
Force GFP_DMA32 allocation for Rockchip IOMMU v2 page tables to fix
NPU operation on systems with >4GB RAM. Without this patch, IOMMU
allocates page tables above 4GB which the NPU cannot access, causing
DMA mapping failures.

Tested on ODROID-M1 with 8GB RAM, kernel 6.18.9-current-rockchip64.
