net: axienet: Fix casting of pointers to u32

Browse source

This driver was casting skb pointers to u32 and storing them as such in
the DMA buffer descriptor, which is obviously broken on 64-bit. The area
of the buffer descriptor being used is not accessed by the hardware and
has sufficient room for a 32 or 64-bit pointer, so just store the skb
pointer as such.
