Fix compiler's view of the alignment of xhci structs. Because the struct
fields are naturally aligned, it is enough to remove __packed.
This lets the compiler generate saner machine code. In particular, now
the compiler does not use lwl/lwr and swl/swr instructions on mips64
for changing xhci descriptors. The descriptors are properly aligned in
memory, so lwl/lwr and swl/swr end up doing a redundant load or store.
