Series platform/surface: Create a platform subdirectory for Microsoft Surface devices | expand

Commit Message

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.

Changes in v2:
 - Do not create a separate MAINTAINERS entry for platform/surface.
   Instead add drivers/platform/surface to x86 platform drivers entry.
   This incorporates recent changes in the x86 platform driver
   MAINTAINERS entry.
 - Fix typo in commit message.
