Enable support for ARM Performance Monitoring Units available in Cortex-A7
and Cortex-A15 CPU cores for Exynos54xx SoCs (5410, 5420 and 5422/5800).
The PMUs interrupts are defined in the common exynos54xx.dtsi device tree,
but the PMUs are enabled and have their interrupt CPU affinity defined
next to each SoC's cpus node.
Tested with perf on Odroid XU4 (Exynos5422):
armv7_cortex_a7 PMU driver: 5 counters available
armv7_cortex_a15 PMU driver: 7 counters available

Pull "Samsung DTS ARM changes for 4.15" from Krzysztof Kozłowski:
1. Add new board: Hardkernel Odroid HC1.
2. Fix incomplete Odroid-XU3/4 thermal-zones definition leading to
possible overheat if first pair of A7+A15 cores is idle but rest of
CPUs are busy.
3. Add capacity-dmips-mhz properties for CPUs of octa-core SoCs.
4. Add power button to Odroid XU3/4.
5. Improvements in Gscaler, HDMI and Mixer blocks on Exynos5.
6. Add suspend quirk to DWC3 USB controller to fix enumeration of
SuperSpeed devices on Odroid XU4.
7. Add HDMI and MHL to Trats2.
8. Cleanups (redundant properties and nodes).

Fix dtc warnings for 'simple_bus_reg' due to leading 0s. Converted using
the following command:
perl -p -i -e 's/\@0+([0-9a-f])/\@$1/g' `find arch/arm/boot/dts -type -f -name '*.dts*'
Dropped changes to ARM, Ltd. boards LED nodes and manually fixed up some
occurrences of uppercase hex.

Odroid XU4 board does not enumerate SuperSpeed devices.
This patch makes exynos5 series chips use USB SUSPHY quirk,
which solves the problem.

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 skeleton.dtsi file was removed in ARM64 for different reasons as
explained in commit ("3ebee5a2e141 arm64: dts: kill skeleton.dtsi").
These also applies to ARM and it will also allow to get rid of the
following DTC warnings in the future:
"Node /memory has a reg or ranges property, but no unit name"
The disassembled DTB are almost the same besides an empty chosen
node being removed and nodes reordered, so it should not have
functional changes.

Move USB 3.0 DWC and 2.0 EHCI/OHCI nodes from exynos5420.dtsi to
exynos54xx.dtsi common for entire family. For Exynos542x/5800 this
should not have functional impact but for Exynos5410 this effectively
adds USB support.

The Exynos5410/542x/5800 are very similar designs. Create a new
DTSI with common nodes to remove DTS duplication. Although currently
only MCT and SysRAM are shared but in future more nodes will be added to
the common file.
The patch should not have functional impact.
