Currently the driver has no MODULE_LICENSE attribute in its source which
results in a kernel taint if I load this:

root@(none):~# modprobe bcm87xx
bcm87xx: module license 'unspecified' taints kernel.

Since the first lines of the source code clearly state:
 * This file is subject to the terms and conditions of the GNU General
 * Public License.  See the file "COPYING" in the main directory of this
 * archive for more details.
I think it's safe to add the MODULE_LICENSE("GPL") macro and thus remove
the kernel taint.

If registering of one of them fails, all already registered drivers
of this module will be unregistered.

Use the new register/unregister functions in all drivers
registering more than one driver.

amd.c, realtek.c: Simplify: directly return registration result.

Tested with broadcom.c
All others compile-tested.

The bcm87xx phys don't support autonegotiation, so don't use it by
default, as otherwise phy_state_machine() will try to enable it (using
c22 requests, which also don't make any sense for the bcm78xx).

Add a driver for BCM8706 and BCM8727 devices.  These are a 10Gig PHYs
which use MII_ADDR_C45 addressing.  They are always 10G full duplex, so
there is no autonegotiation.  All we do is report link state and send
interrupts when it changes.

If the PHY has a device tree of_node associated with it, the
"broadcom,c45-reg-init" property is used to supply register
initialization values when config_init() is called.
