Add the device tree bindings and the accompanying documentation
for the TI DP83867 Giga bit ethernet phy driver.

The original document was from:
    [commit 2a10154abcb75ad0d7b6bfea6210ac743ec60897 from the Linux kernel]

Not all devices use the same internal delay or fifo depth.
Add the ability to set the internal delay for rx or tx and the
fifo depth via the devicetree.  If the value is not set in the
devicetree then set the delay to the default.

If devicetree is not used then use the default defines within the
driver.

Nack from me. Just follow Linux binding instead of create new one.

Why a nack?

This comes from the Linux kernel mainline code I submited.  I am not creating anything new.
This technically should have come in with the original port of the driver I pushed to the Linux kernel.

But I defer to the Tom for the resolution.

Well boo.  I know what you are referring to now.

I did not use ti,tx-internal-delay and ti,rx-internal-delay.  I used ti,tx-int-delay and ti,rx-int-delay

which is wrong.  Here come v3 with the update
