The Vybrid based Colibri modules provide a on-module PHY which is
connected to the second FEC instance FEC1. Since the on-module
Ethernet port is considered as primary ethernet interface, alias
fec1 as ethernet0. This also makes sure that the first MAC address
provided by the boot loader gets assigned to the FEC instance used
for the on-module PHY.

The NAND flash memory populated on Colibri VF61 allows faster NAND
timings than the flash memory on VF50. Additionally, due to divider
limitations, VF61 did clock the flash even slower than VF50. Assign
the NFC clock in the module specific device trees vf500-colibri.dtsi
and vf610-colibri.dtsi respectively.
This increases raw read speed on Colibri VF61 by about 20%.

Add missing reg properties to AIPS bus and Cortex-A5's PMU unit.
This change avoids the following warnings:
Warning (unit_address_vs_reg): Node /soc/aips-bus@40000000 has a unit
name, but no reg property
Warning (unit_address_vs_reg): Node /soc/aips-bus@40080000 has a unit
name, but no reg property
Warning (unit_address_vs_reg): Node /soc/aips-bus@40080000/pmu@40089000
has a unit name, but no reg property
