ARM: imx6ul-14x14-evk: Fix suspend over nfs by phy

Right now attempting doing suspend/resume while root is mounted over NFS
hangs on imx6ul-14x14-evk. This is happening because ksz8081 phy fixups are
lost on resume.

Fix this by using equivalent devicetree properties instead of a phy fixup
and handling those properties on resume in the micrel driver.

In theory it might now be possible to remove the phy fixup from mach-imx6ul
entirely but it is possible that this would break other imx6ul boards which
use the same phy. The solution would be to patch their dts but it's not
clear how to identify affected boards.

This code is shared with imx6ull-14x14-evk but 6ull suspend needs an
unrelated patch: https://lkml.org/lkml/2017/5/30/584

This is something of a corner case so there is no CC: stable.

Changes since v1: https://lkml.org/lkml/2017/5/30/672
 * Split a kszphy_config_reset function for stuff shared between
config_init and resume. Calling config_init directly could be an option but
on some HW variants it does extra stuff like parsing devicetree options.
That would not be appropriate for resume code.

Auto-loading of the Marvell DSA driver has stopped working with recent
kernels.  This seems to be due to the change of binding for DSA devices,
moving them from the platform bus to the MDIO bus.

In order for module auto-loading to work, we need to provide a MODALIAS
string in the uevent file for the device.  However, the device core does
not automatically provide this, and needs each bus_type to implement a
uevent method to generate these strings.  The MDIO bus does not provide
such a method, so no MODALIAS string is provided:

.# cat /sys/bus/mdio_bus/devices/f1072004.mdio-mii\:04/uevent
DRIVER=mv88e6085
OF_NAME=switch
OF_FULLNAME=/soc/internal-regs/mdio@72004/switch@4
OF_COMPATIBLE_0=marvell,mv88e6085
OF_COMPATIBLE_N=1

In the case of OF-based devices, the solution is easy -
of_device_uevent_modalias() does the work for us.  After this is done,
the uevent file looks like this:

.# cat /sys/bus/mdio_bus/devices/f1072004.mdio-mii\:04/uevent
DRIVER=mv88e6085
OF_NAME=switch
OF_FULLNAME=/soc/internal-regs/mdio@72004/switch@4
OF_COMPATIBLE_0=marvell,mv88e6085
OF_COMPATIBLE_N=1
MODALIAS=of:NswitchT<NULL>Cmarvell,mv88e6085

which results in auto-loading of the Marvell DSA driver on Clearfog
platforms.

During PCI error recovery process, specifically on eeh_err_detected()
we might have a NULL netdev struct, hence a direct dereference will
lead to a kernel oops. This was observed with latest upstream kernel
(v4.12-rc2) on Chelsio adapter T422-CR in PowerPC machines.

This patch checks for NULL pointer and avoids the crash, both in
eeh_err_detected() and eeh_resume(). Also, we avoid to trigger
a fatal error or to try disabling interrupts on FW during PCI
error recovery, because: (a) driver might not be able to accurately
access PCI regions in this case, and (b) trigger a fatal error
_during_ the recovery steps is a mistake that could prevent the
recovery path to complete successfully.

When starting or stopping an aggregation session, one of the steps
is that the driver calls back to mac80211 that the start/stop can
proceed. This is handled by queueing up a fake SKB and processing
it from the normal iface/sdata work. Since this isn't flushed when
disassociating, the following race is possible:

 * associate
 * start aggregation session
 * driver callback
 * disassociate
 * associate again to the same AP
 * callback processing runs, leading to a WARN_ON() that
   the TID hadn't requested aggregation

If the second association isn't to the same AP, there would only
be a message printed ("Could not find station: <addr>"), but the
same race could happen.

Fix this by not going the whole detour with a fake SKB etc. but
simply looking up the aggregation session in the driver callback,
marking it with a START_CB/STOP_CB bit and then scheduling the
regular aggregation work that will now process these bits as well.
This also simplifies the code and gets rid of the whole problem
with allocation failures of said skb, which could have left the
session in limbo.

I tried to make this patch as small as possible to ease its backport,
instead of being super clean. Note that we believe that only ipv4 dst
need to take care of the metric refcount. But if this is wrong,
this patch adds the basic infrastructure to extend this to other
