gralloc: Send first 2 FB buffers to carveout and next to IOMMU
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.
