net: bcmgenet: enable MoCA link state change detection

Currently, MoCA fixed PHYs are always in link-up state, regardless of
whether the link is actually up or not.

Add code to properly detect MoCA link state changes and to reflect the
new state in MoCA fixed PHY. Only GENET V3 and V4 MACs are capable of
detecting MoCA link state changes.

The code works as follows:
1. GENET MAC detects MoCA link state change and issues UMAC_IRQ_LINK_UP
   or UMAC_IRQ_LINK_DOWN interrupt.
2. Link up/down interrupt is processed in bcmgenet_irq_task(), which
   calls phy_mac_interrupt().
3. phy_mac_interrupt() updates the fixed PHY phydev->link and kicks
   the PHY state machine.
4. PHY state machine proceeds to read the fixed PHY link status
   register.
5. When the fixed PHY link status register is being read, the new
   function bcmgenet_fixed_phy_link_update() gets called. It copies
   the fixed PHY phydev->link value to the fixed PHY status->link.
6. PHY state machine receives the new link state of the fixed PHY.
7. MoCA fixed PHY link state now correctly reflects the real MoCA
   hardware link state.

net/macb: fix capabilities configuration

Capabilities configuration by macb_configure_caps() was moved far too late by
421d9df0628b (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.

netlink: access functions for IP address 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

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

It's possible that due to errors [either on PCI or on device itself]
