Gralloc uses the GRALLOC_USAGE_HW_FB flag to allocate memory from carveout. This is fine for primary framebuffer, but for external framebuffer we need IOMMU heap buffers, since the ioctls for external work with those. Ideally, the primary buffers also need to come from IOMMU heap, which is ongoing work. This patch allocates the first 2 FB buffer requests (assuming they are for primary) from carveout and allocates all subsequent buffers from IOMMU heap.
