commit bed903167ae5b5532eda5d7db26de451bd232da5 upstream.

Commit ef72171b ("arm64: dts: exynos: Remove unneeded address space
mapping for soc node") changed the address and size cells in root node from
2 to 1, but /memory nodes for the affected boards were not updated. This
went unnoticed on Exynos5433-based TM2(e) boards, because they use u-boot,
which updates /memory node to the correct values. On the other hand, the
mentioned commit broke boot on Exynos7-based Espresso board, which
bootloader doesn't touch /memory node at all.

This patch reverts commit ef72171b ("arm64: dts: exynos: Remove
unneeded address space mapping for soc node"), so Exynos5433 and Exynos7
SoCs again matches other ARM64 platforms with 64bit mappings in root
node.

Replace hard-coded values of type of GIC interrupt and its flags with

Signed-off-by: NKrzysztof Kozlowski <krzk@kernel.org>

Interrupt of type IRQ_TYPE_NONE is not allowed for GIC interrupts and
generates an error:
	genirq: Setting trigger mode 0 for irq 16 failed (gic_set_type+0x0/0x68)

The GIC requires shared interrupts to be edge rising or level high.
Platform declares support for both.  Arbitrarily choose level high
everywhere hoping it will work on each platform.

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).
