Adds a phy_mask field to struct mii_bus and uses it. This field
indicates each phy address to be ignored when probing the mdio bus.
This support is needed for the fs_enet and ibm_emac drivers to be
converted to the generic phy layer among other drivers. Many systems
lock up on probing certain phy addresses or probing doesn't return
0xffff when nothing is found at the address. A new driver I'm
working on also makes use of this mask.

In PM v1, all devices were called at SUSPEND_DISABLE level. Then
all devices were called at SUSPEND_SAVE_STATE level, and finally
SUSPEND_POWER_DOWN level. However, with PM v2, to maintain
compatibility for platform devices, I arranged for the PM v2
suspend/resume callbacks to call the old PM v1 suspend/resume
callbacks three times with each level in order so that existing
drivers continued to work.
Since this is obsolete infrastructure which is no longer necessary,
we can remove it. Here's an (untested) patch to do exactly that.

drivers/net/phy/phy.c is broken on s390; it uses enable_irq() and friends
and these do not exist on s390. Marked as broken for now.

When building with CONFIG_PHYLIB=y on Itanium, I see:
`mdio_bus_exit' referenced in section `.init.text' of
drivers/built-in.o: defined in discarded section `.exit.text' of
drivers/built-in.o
I believe that mdio_bus_exit should not be declared __exit, because it is
referencesd from __init sections in, say, phy_init().

Fix remaining bits of u32 vs. pm_message confusion. Should not break
anything.

This patch adds back the code that was taken out, thus re-enabling:
* The PHY Layer to initialize without crashing
* Drivers to actually connect to PHYs
* The entire PHY Control Layer
This patch is used by the gianfar driver, and other drivers which are in
development.

- unexport symbols never used outside of home module
- remove dead code
- remove CONFIG_PHYCONTROL, make it unconditionally enabled

Includes fixes for problems noted by Adrian Bunk, Andrew Morton,
and one other person lost in the annals of history (and email folders).

ethernet drivers to remain as ignorant as is reasonable of the connected
PHY's design and operation details.
