The VExpress development platform has an external expansion bus which
can be used for additional hardware (e.g. LogicTile Express daughter
boards).
Add this bus to the VExpress CoreTile device-trees.The bus is described
for a CoreTile occupying site 1.

Commit b993734718 ("scripts/dtc: Update to upstream version 53bf130b1cdd")
added warnings on node name unit-address presence/absence mismatch in
the device trees.
This patch fixes those warning on all the vexpress platforms where
unit-address is present in node name while the reg/ranges property is
not present.

The ARM perf core code used to rely on the pmu node being
compatible with "arm,cortex-a9-pmu", even when the PMUs
of the different Cortex-A processors are not really
compatible... This is no longer required and actually
became harmful, so remove all the offending values
from Versatile Express DTS files.

As the wdt nodes have the gic as their interrupt-parent, their
interrupts property should be 3 cells in format described in the gic
devicetree binding document.
This patch fixes the interrupts property in the wdt nodes to be in the
correct format.

The way the VE motherboard Device Trees were constructed
enforced naming and structure of daughterboard files. This
patch makes it possible to simply include the motherboard
description anywhere in the main Device Tree and retires
the "arm,v2m-timer" alias - any of the motherboard SP804
timers will be used instead.

* Added extra regs for A15 VGIC
* Added A15 architected timer node
* Split A5 and A9 TWD nodes into two separate ones for timer
and watchdog; interrupt definitions fixed on the way
* Fixed typo in A5 GIC compatible value

This patch adds Device Tree file for the CoreTile Express A15x2
(V2P-CA15) with Test Chip 1.
As the chip's GIC has 160 interrupt inputs and equivalent SMM
(FPGA) has GIC synthesised with 256 interrupts, NR_IRQS is
increased.
