Implement the ndo_setup_tc() operation with 2 traffic classes.
Current Solarstorm controllers do not implement TX queue priority, but
they do allow queues to be 'paced' with an enforced delay between
packets. Paced and unpaced queues are scheduled in round-robin within
two separate hardware bins (paced queues with a large delay may be
placed into a third bin temporarily, but we won't use that). If there
are queues in both bins, the TX scheduler will alternate between them.
If we make high-priority queues unpaced and best-effort queues paced,
and high-priority queues are mostly empty, a single high-priority queue
can then instantly take 50% of the packet rate regardless of how many
of the best-effort queues have descriptors outstanding.
We do not actually want an enforced delay between packets on best-
effort queues, so we set the pace value to a reserved value that
actually results in a delay of 0.

efx_channel_get_{rx,tx}_queue() currently return NULL if the channel
isn't used for traffic in that direction. In most cases this is a
bug, but some callers rely on it as an existence test.
Add existence test functions efx_channel_has_{rx_queue,tx_queues}()
and use them as appropriate.
Change efx_channel_get_{rx,tx}_queue() to assert that the requested
queue exists.
Remove now-redundant initialisation from efx_set_channels().

efx_hard_start_xmit() needs to implement a mapping which is the
inverse of tx_queue::core_txq. Move the initialisation of
tx_queue::core_txq next to efx_hard_start_xmit() to make the
connection more obvious.

This fixes warnings when CONFIG_DMA_API_DEBUG=y:
NULL NULL: DMA-API: device driver tries to free DMA memory it has not allocated [device address=0x000000004781a020] [size=64 bytes]
net eth0: DMA-API: device driver frees DMA memory with different size [device address=0x000000004781a020] [map size=2048 bytes] [unmap size=64 bytes]
Moreover pass the platform device to dma_{,un}map_single which makes
more sense because the logical network device doesn't know anything
about dma.
Passing the platform device was a suggestion by Lothar Waßmann.

Moreover stop listing all i.MX platforms featuring a FEC, and use

instead. This might make it easier to add new platforms.

Bosch C_CAN controller is a full-CAN implementation which is compliant
to CAN protocol version 2.0 part A and B. Bosch C_CAN user manual can be
obtained from:
http://www.semiconductors.bosch.de/media/en/pdf/ipmodules_1/c_can/users_manual_c_can.pdf
This patch adds the support for this controller.
The following are the design choices made while writing the controller
driver:
1. Interface Register set IF1 has be used only in the current design.
2. Out of the 32 Message objects available, 16 are kept aside for RX
purposes and the rest for TX purposes.
3. NAPI implementation is such that both the TX and RX paths function
in polling mode.
