platform: Add ARM64 platform directory

Some ARM64 based laptops and computers require vendor/board specific
drivers for their embedded controllers. Even though usually the most
important functionality of those devices is implemented inside ACPI,
unfortunately Linux doesn't currently have great support for ACPI on
platforms like Qualcomm Snapdragon that are used in most ARM64 laptops
today. Instead Linux relies on Device Tree for Qualcomm based devices
and it's significantly easier to reimplement the EC functionality in
a dedicated driver than to make use of ACPI code.

This commit introduces a new platform/arm64 subdirectory to give a
place to such drivers for EC-like devices.

A new MAINTAINERS entry is added for this directory. Patches to files in
this directory will be taken up by the platform-drivers-x86 team (i.e.
Hans de Goede and Ilpo Järvinen) with additional review from Bryan
O'Donoghue to represent ARM64 maintainers.

there has such an if. So let's remove it.

While at it also move the x86/Kconfig include to the end of the file
for alphabetical sorting.

platform: Add Surface platform directory

It may make sense to split the Microsoft Surface hardware platform
drivers out to a separate subdirectory, since some of it may be shared
between ARM and x86 in the future (regarding devices like the Surface
Pro X).

Further, newer Surface devices will require additional platform drivers
for fundamental support (mostly regarding their embedded controller),
which may also warrant this split from a size perspective.

This commit introduces a new platform/surface subdirectory for the
Surface device family, with subsequent commits moving existing Surface
drivers over from platform/x86.

A new MAINTAINERS entry is added for this directory. Patches to files in
this directory will be taken up by the platform-drivers-x86 team (i.e.
Hans de Goede and Mark Gross) after they have been reviewed by
Maximilian Luz.

The community has been maintaining x86 vendor-specific
platform specific drivers under /drivers/misc/ for a few years.
The oldest ones started life under drivers/acpi.
They moved out of drivers/acpi/ because they don't actually
implement the ACPI specification, but either simply
use ACPI, or implement vendor-specific ACPI extensions.

In the future we anticipate...
drivers/misc/ will go away.
other architectures will create drivers/platform/<arch>
