User i/o register EMAC_USRIO or GMAC_UR can be found on both macb and gem
flavors of the peripheral. By using the proper accessor, we can add it to the
register dump feature of ethtool.
Increment the version of this API so it can be noticed from user space.

As accessing the peripheral registers need the clocks to be set, we have to
enable them as soon as possible. Their configuration depend on the type of
device used and determined by the DT compatible string. That lead to add
another initialization function in the DT configuration structure.
As the device private structure length depend on an information read in the
registers, we have to store the clock pointers in temporary variables before
feeding the structure fields.

Capabilities configuration by macb_configure_caps() was moved far too late by
421d9df0 (net/macb: merge at91_ether driver into macb driver) which would
lead to badly configured hardware.
So, move this function to early probe and modify its prototype to re-gain its
original behavior.
DT data retrieval is also moved to simplify the probe code flow.

When merging at91_ether and macb driver during 421d9df0 (net/macb: merge
at91_ether driver into macb driver) the probe function has been split. The code
dealing with initialization of queues is now moved in macb_init() which needs
information computed in the parent macb_probe() function.
So, add the queue_mask information to the private structure and use it when
needed in macb_init().

netlink: access functions for IP address attributes

There are many places that read or write IP addresses to netlink attributes.
With IPv6 addresses, every such place currently has to use generic nla_put
and nla_memcpy. Implementing IPv6 address access functions simplify things
and makes the code more intelligible. IPv4 address access functions has
lesser value but it would be better to be consistent between IPv6 and IPv4
and they still serve as documentation.

The conversion is straightforward and the resulting patches are not that
large, thus I kept all the changes in the patches that introduce the access
functions. If anyone prefers to split the definition of access functions and
the conversion and/or break it out by network protocols, please let me know.

While doing the conversion, I came across ugly typecasting in
inetpeer_addr_base and xfrm_address_t when dealing with IPv6 addresses.
Instead of introducing more of this, I cleaned it up. Those are the first
two patches, serving as a prerequisite to the latter two.
