PHY drivers support loopback mode, but it is not possible to select the
speed of the loopback mode. The speed is chosen by the set_loopback()
operation of the PHY driver. Same is valid for genphy_loopback().
There are PHYs that support loopback with different speeds. Extend
set_loopback() to make loopback speed selection possible.

'struct mdio_device_id' is not modified in these drivers.
Constifying these structures moves some data to a read-only section, so
increase overall security.
On a x86_64, with allmodconfig, as an example:
Before:
======

An interrupt handler was added to the driver as well as functions
to enable interrupts at the phy.
There are several interrupts maskable at the phy, but only link change
interrupts are handled by the driver yet.
