Handle the larger flash memories on newer boards:

- get the size and number of sectors by probing the flash
- writes and erases can take longer, adjust the timeouts for these operations
- the FW image can be at different locations depending on flash size,
  find its location dynamically as well.

Reviewed RX descriptor functions against the HAL sources. Some minor changes:

  - check size before making changes to the descriptor

  - whitespace

  - add comments about 5210 timestamps. this needs to be adressed later!

  - FIFO overrun error only available on 5210

  - rs_phyerr should not be OR'ed

  - clear the whole ath5k_rx_status structure before using, instead of
    zeroing specific fields.

SKBs hold onto resources that can't be held indefinitely, such as TCP
socket references and netfilter conntrack state.  So if a packet is left
in TX ring for a long time, there might be a TCP socket that cannot be
closed and freed up.

Current blackfin EMAC driver always reclaim and free used tx skbs in future
transfers. The problem is that future transfer may not come as soon as
possible. This patch start a timer after transfer to reclaim and free skb.
There is nearly no performance drop with this patch.

TX interrupt is not enabled because of a strange behavior of the Blackfin EMAC.
If EMAC TX transfer control is turned on, endless TX interrupts are triggered
no matter if TX DMA is enabled or not. Since DMA walks down the ring automatically,
TX transfer control can't be turned off in the middle. The only way is to disable
TX interrupt completely.
