In preparation for adding support for Wirespeed/downshift, we need to
change bcm_phy_eee_enable() to allow enabling or disabling EEE, so make
the function take an extra enable/disable boolean parameter and rename
it to illustrate it sets EEE, not necessarily just enables it.

Broadcom's Wirespeed feature allows us to configure how auto-negotiation
should behave with fewer working pairs of wires on a cable. Add support
code for retrieving and setting such downshift counters using the
recently added ethtool downshift tunables.

We are going to need these functions to implement support for Broadcom
Wirespeed, aka downshift.

This patch adds the Broadcom phy library to consolidate common
interfaces shared by Broadcom phy's.
Moved the common interfaces to the 'bcm-phy-lib.c' and updated
the Broadcom PHY drivers to use the new APIs.
