The ARM architected timer specification mandates that the interrupt
associated with each timer is level triggered (which corresponds to
the "counter >= comparator" condition).

A number of DTs are being remarkably creative, declaring the interrupt
to be edge triggered. A quick look at the TRM for the corresponding ARM
CPUs clearly shows that this is wrong, and I've corrected those.
For non-ARM designs (and in the absence of a publicly available TRM),
I've made them active low as well, which can't be completely wrong
as the GIC cannot disinguish between level low and level high.

The respective maintainers are of course welcome to prove me wrong.

While I was at it, I took the liberty to fix a couple of related issue,
such as some spurious affinity bits on ThunderX, and their complete
absence on ls1043a (both of which seem to be related to copy-pasting
from other DTs).

The convention in these files is to use lowercase for "0x" prefixes and for
the hex constants themselves, but a few changes didn't follow that
convention, which makes the file annoying to read.

Use lowercase consistently for the hex constants.  No functional change
intended.

This patch adds DTS entries for Designware I2C controller used in

APM X-Gene v1 SoC has 2 I2C controllers. On Mustang board,
I2C1 is used to implement proxy I2C interface; I2C1 can be
used as I2C slave port (for BMC) or as I2C master port (if
no BMC is used). Only I2C1 DT entry is added in this
patch with default status as 'disabled'.
