The BF518 has a PTP time unit that works in a similar way to other MAC
based clocks, like gianfar, ixp46x, and igb. This patch adds support for
using the blackfin as a PHC. Although the blackfin hardware does offer a
few ancillary features, this patch implements only the basic operations.
Compile tested only.

This patch replaces the sys time stamps and timecompare code with simple
raw hardware time stamps in nanosecond resolution. The only tricky bit is
to find a PTP Hardware Clock period slower than the input clock period
and a power of two.
Compile tested only.

Adapt adi ethernet driver to changes in bfin_get_ether_addr()
from arch/blackfin. bfin_get_ether_addr() returns now a state.
Set a random mac address via new eth_hw_addr_random() in case
the return value is not 0.
Reset the state to NET_ADDR_PERM as soon as the MAC get
changed via .ndo_set_mac_address.
v2: change the logic to reduce unneeded checks

Move the Analog Devices Inc driver into drivers/net/ethernet/adi/ and
make the necessary Kconfig and Makefile changes.
