This patch improves the logic used by the mvneta driver to find a MAC
address for a particular interface. Until now, it was only looking at
the Device Tree, and if no address was found, was falling back to
generating a random MAC address.
This patch adds the intermediate solution of reading the MAC address
from the hardware registers, in case it has been set by the
bootloader. So the order is now:
1) MAC address from the Device Tree
2) MAC address from the hardware registers
3) Random MAC address
This requires moving the MAC address initialization a little bit later
in the ->probe() code, because it now requires the hardware registers
to be remapped.

76723bca28 "net: mv643xx_eth: add DT parsing support" added a
dummy mv643xx_eth_shared_of_probe() fallback function with a
typo.
This adds the missing semicolon so we can build without CONFIG_OF
again, and changes both dummy functions to the more conventional
"static inline" syntax, which can avoid potential problems with
the empty macro.

====================
this is a pull-request for net-next/master. It consists of two patches
by Fabio Estevam, cleaning up the flexcan driver (remove default
pinctrl and switch to SIMPLE_DEV_PM_OPS). A patch by me to simplify the
Kconfig [1] handling for flexcan. And a patch by Jingoo Han that
converts the can drivers to use platform_{get,set}_drvdata().
[1] My patch touches arch/{arm,powerpc}, so I collected Acked-bys from
Arnd Bergmann, Shawn Guo and Benjamin Herrenschmidt.

Use the wrapper functions for getting and setting the driver data using
platform_device instead of using dev_{get,set}_drvdata() with &pdev->dev,
so we can directly pass a struct platform_device.
Also, unnecessary dev_set_drvdata() is removed, because the driver core
clears the driver data to NULL after device_release or on probe failure.

commit 13d82bf5 (ipv4: Fix flushing of cached routing informations)
added the support to flush learned pmtu information.
However, using rt_genid is quite heavy as it is bumped on route
add/change and multicast events amongst other places. These can
happen quite often, especially if using dynamic routing protocols.
While this is ok with routes (as they are just recreated locally),
the pmtu information is learned from remote systems and the icmp
notification can come with long delays. It is worthy to have separate
genid to avoid excessive pmtu resets.

Forcing uninitialized state allows us to upgrade and reinitialize the adapter.
FW_VERSION_T4 = 1.4.0.0
FW_VERSION_T5 = 0.0.0.0
At this point driver supports above and greater than above version of firmware.
If it doesn't find the required firmware version than it forces the adapter to
be reinitialized as shown below.
1) If FW_ON_ADAPTER < FW_VERSION and we're the MASTER_PF force uninitialized
state and a FW upgrade if available.
- If FW_ON_ADAPTER < /lib/firmware/cxgb4/t*fw.bin we will update the
adapters FW.
- If FW_ON_ADAPTER >= /lib/firmware/cxgb4/t*fw.bin don't upgrade FW.
- If upgrade_fw() fails force reinitialization of the adapter anyways,
it might still work.
Either way forcing the uninitialized state allows cxgb4 reinitialize FW.
2) If FW_ON_ADAPTER >= FW_VERSION driver follows normal path.
