This patch enables LAN9500 family devices to wake from suspend
on either link up or link down events
It also adds _nopm versions of mdio access functions, so we can
safely call them from suspend and resume functions

Instead of storing the number of wake-up frame filter registers
in the pdata structure, this patch changes the driver to detect
the type of device we have and store its available features.
The new two features will be used in future patches.
This patch is intended to have no change in behaviour.

This patch adds support for wol wakeup on unicast, broadcast,
multicast and arp frames.
The wakeup filter code isn't pretty, but it works.

Removes unnecessary variables as smsc95xx_write_reg takes its
value by parameter. Early versions passed this parameter by
reference.
Also replace hardcoded interrupt status value with a #define

SMSC LAN9500 has dual purpose GPIO/LED pins, and by default at power-on
these are configured as GPIOs. This means that if LEDs are fitted they
won't ever light.
This patch sets them to be LED outputs for speed, duplex and
link/activity.
