The PHYs hwtstamp callback are still getting the timestamp config from
ifreq and using copy_from/to_user.
Get rid of these functions by using timestamp configuration in parameter.
This also allow to move on to kernel_hwtstamp_config and be similar to
net devices using the new ndo_hwstamp_get/set.
This adds the possibility to manipulate the timestamp configuration
from the kernel which was not possible with the copy_from/to_user.

While PHY time stamping drivers can simply attach their interface
directly to the PHY instance, stand alone drivers require support in
order to manage their services. Non-PHY MII time stamping drivers
have a control interface over another bus like I2C, SPI, UART, or via
a memory mapped peripheral. The controller device will be associated
with one or more time stamping channels, each of which sits snoops in
on a MII bus.
This patch provides a glue layer that will enable time stamping
channels to find their controlling device.

Currently the stack supports time stamping in PHY devices. However,
there are newer, non-PHY devices that can snoop an MII bus and provide
time stamps. In order to support such devices, this patch introduces
a new interface to be used by both PHY and non-PHY devices.
In addition, the one and only user of the old PHY time stamping API is
converted to the new interface.
