cris build fixes: update eth_v10.c ethernet driver

New (updated) version of ethernet driver for cris v10.

- First steps to simplify and make the MII code more similar
  between the etrax100 and etraxfs ports.

- Start the transmit queue before enabling tx interrupts
  to avoid race with the first frame.

- Flip the comparition statement to stick to physical addresses
  to avoid phys_to_virt mapping a potential null pointer.
  This was not an error but the change simplifies debugging
  of address-space mappings.

- Made myPrevRxDesc local to e100_rx since it was only used there.
  Fixed out of memory handling in e100_rx.  If dev_alloc_skb() fails
  persistently the system is hosed anyway but at least it won't
  loop in an interrupt handler.

- Correct some code formatting issues.

- Add defines SET_ETH_ENABLE_LEDS, SET_ETH_DISABLE_LEDS
  and SET_ETH_AUTONEG used in new cris v10 ethernet driver.
