platform/x86: Move existing HP drivers to a new hp subdir

The purpose of this patch is to provide a central location where all
HP related drivers are found. HP drivers will recide under
drivers/platform/x86/hp directory.

Introduce changes to Kconfig file to list all HP driver under "HP X86
Platform Specific Device Drivers" menu option. Additional changes
include update MAINTAINERS file to indicate hp related drivers new
path.
