Implement MDIO bus read/write functions, initialize the bus and scan for
the PHY when phylib is enabled. Limit PHY speeds to 10/100 Mbps.

The ethoc device can be configured to have a private memory region
instead of having access to the main memory. In that case egress packets
must be copied into that memory for transmission and pointers to that
memory need to be passed to net_process_received_packet or returned from
the recv callback.

Addresses used in buffer descriptors and passed in platform data or
device tree are physical. Addresses used by CPU to access packet data
and registers are virtual. Don't mix these addresses and use virt_to_phys
for translation.

device configuration from the device tree.

Extract reusable parts from ethoc_init, ethoc_set_mac_address,
ethoc_send and ethoc_receive, move the rest under #ifdef CONFIG_DM_ETH.
Add U_BOOT_DRIVER, eth_ops structure and implement required methods.

Don't use physical base address of registers directly, ioremap it first.
Save pointer in private struct ethoc and use that struct in all internal
functions.

Update the naming convention used in the network stack functions and
variables that Ethernet drivers use to interact with it.
This cleans up the temporary hacks that were added to this interface
along with the DM support.
This patch has a few remaining checkpatch.pl failures that would be out
of the scope of this patch to fix (drivers that are in gross violation
of checkpatch.pl).

Use size_t type for positive offsets instead of the loff_t type. The
later is defined as long long, which is larger than the pointer type
on OpenRISC architecture and therefore the following warning was
generated:
"warning: cast to pointer from integer of different size"

These are all the files which use the API incorrectly but did not get
built using MAKEALL -a powerpc|arm. I have no compiler for them, but
the remaining issues should be far less than without this patch.
Any outstanding issues are left to the maintainers of boards that use
these drivers.
