An af_iucv stress test showed -EPIPE results for sendmsg()
calls. They are caused by quiescing a path even though it has
been already severed by peer. For IUCV transport shutdown()
consists of 2 steps:
(1) sending the shutdown message to peer
(2) quiescing the iucv path
If the iucv path between these 2 steps is severed due to peer
closing the path, the quiesce step is no longer needed.

The link adjustment callback can be called as frequently as desired
by the PHY library, as such, let's avoid doing a Read/Modify/Write
sequence if nothing changed, since these register accesses can be
expensive.

Update bcmgenet_suspend() to prepare the hardware for being put into
Wake-on-LAN mode if the device can wakeup the system, and Wake-on-LAN is
enabled. Whether we resume from Wake-on-LAN or not, make sure that
bcmgenet_resume() disables the UniMAC MagicPacket matching mode and puts
the hardware in a state where it can receive all incoming packets.

bcmgenet_wol_resume() will create an unbalanced clock state for the
wol_clk clock pointer since everywhere else in the code, we always call
clk_prepare_enable() and clk_disable_unprepare(). This function also
calls init_umac() which is neither correct nor necessary since
bcmgenet_resume() and bcmgenet_open() already does that.

Finally calling bcmgenet_wol_resume() in bcmgenet_open() is not correct,
since the interface would not have been able to put us in Wake-on-LAN
mode if it was not UP before.

Handle UMAC_IRQ_MPD_R interrupt bit in our workqueue to make sure that
we properly re-configure the GENET adapter from Wake-on-LAN.

bcmgenet_power_up() makes sure that we will not leave the UniMAC
hardware in MagicPacket matching mode, since that would prevent any
other packet from being received.
