bfin_mac: offer a PTP Hardware Clock.
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.
