Samsung DTS ARM changes for v5.1

1. Extend support for Aries family of mobile devices (e.g. Samsung
   Galaxy S) based on S5Pv210 SoC: DRM Rotator, FIMD, PWM vibrator,
   power off, touchscreen, Broadcom BCM4329 Bluetooth and cpufreq.
2. Remove hardcoded bootargs on Galaxy S family (proper support in
   U-Boot).
3. Fix minor DTC warnings.
4. Fix Exynos4412 Odroid X2/U3 conflicting eMMC GPIO settings and regulator
   properties.
5. Fix the eMMC RTSN pin breaking proper reboot on X2.

The 'arm,armv8' compatible string is only for software models. It adds
little value otherwise and is inconsistently used as a fallback on some
platforms. Remove it from those platforms.

This fixes warnings generated by the DT schema.

Remove the usage of skeleton.dtsi in the remaining dts files. It was
deprecated since commit 9c0da3cc ("ARM: dts: explicitly mark
skeleton.dtsi as deprecated"). This will make adding a unit-address to
memory nodes easier.

The main tricky part to removing skeleton.dtsi is we could end up with
no /memory node at all when a bootloader depends on one being present. I
hacked up dtc to check for this condition.

A CPUfreq driver, like the scpi driver used on Juno boards, which
provide the Energy Model with power cost information via the PM_OPP
of_dev_pm_opp_get_cpu_power() function, do need the
dynamic-power-coefficient (C) in the device tree.

Method used to obtain the C value:

C is computed by measuring energy (E) consumption of a frequency domain
(FD) over a 10s runtime (t) sysbench workload running at each Operating
Performance Point (OPP) affine to 1 or 2 CPUs of that FD while the other
CPUs of the system are hotplugged out.

By definition all CPUs of a FD have the the same micro-architecture. An
OPP is characterized by a certain frequency (f) and voltage (V) value.
The corresponding power values (P) are calculated by dividing the delta
of the E values between the runs with 2 and 1 CPUs by t.

With n data tuples (P, f, V), n equal to number of OPPs for this
frequency domain, we can solve C by:

P = Pstat + Pdyn

P = Pstat + CV²f

Cx = (Px - P1)/(Vx²fx - V1²f1) with x = {2, ..., n}

The C value is the arithmetic mean out of {C2, ..., Cn}.

Since DVFS is broken on Juno r1, no dynamic-power-coefficient
information has been added to its dts file.

Fixed Virtual Platforms(FVP) Base RevC model is an emulated Arm platform
with GICv3, PCIe, SMMUv3 and various other features. These are available
free of charge on the Arm Community website at Arm Development
Platforms[1].

It resembles the Foundation Platform, which is a simple FVP that
includes an Armv8‑A AEM processor model but this has two cluster of four
cores, a CCI-550 interconnect, an SMMU and two PCI devices.

In order to enable development of software, let's add a description of
the Revison C version of Base platform.

The documentation for this FVP model is available @[2] for reference.

There are macros that exist to indicate the GIC specific flags and
custom cell values as per the GIC DT bindings. It's used in most of the
places in these DTS files but not all. To maintain consistency, lets
use the macros at all the places.

Since DTC doesn't even warn is any cells are missing, it's very hard to
debug if that's the case. Changing to use macros avoids missing cells/
columns.

Pull x86 fixes from Thomas Gleixner:
 "A set of fixes for x86:

   - Fix the swapped outb() parameters in the KASLR code

   - Fix the PKEY handling at fork which missed to preserve the pkey
     state for the child. Comes with a test case to validate that.

   - Fix the entry stack handling for XEN PV to respect that XEN PV
     systems enter the function already on the current thread stack and
     not on the trampoline.

   - Fix kexec load failure caused by using a stale value when the
     kexec_buf structure is reused for subsequent allocations.

   - Fix a bogus sizeof() in the memory encryption code

   - Enforce PCI dependency for the Intel Low Power Subsystem

   - Enforce PCI_LOCKLESS_CONFIG when PCI is enabled"
