  dp8393x: put the DMA buffer in the state structure

Move it from the stack.

It's only 24 bytes, and this simplifies the dp8393x_get()/
dp8393x_put() interface.

  dp8393x: fix dp8393x_receive()

RXpkt.in_use is always 16 bit wide, but when the bus access mode is 32bit
and the endianness is big, we must access the second word and not the
first. This patch adjusts the offset according to the size and endianness.

This fixes DHCP for Q800 guest.
