net: bcmgenet: disable clock before register_netdev

As soon as register_netdev() is called, the network device notifiers are
running which means that other parts of the kernel, or user-space
programs can call the network device ndo_open() callback and use the

Disable the Ethernet device clock before we register the network device
such that we do not create the following situation:

CPU0				CPU1

and leave the hardware block gated off, while we think it should be
gated on.
