[PATCH v7 00/17] OpenSBI Kconfig Support

In future, we will see more drivers in OpenSBI for system reset, serial port,
power management, etc platform specific devices. We need platform specific
compile time configuration to allow users control the size of OpenSBI generic
firmware binaries by only enabling desired drivers. In other words, users
should be allowed to restrict the set of RISC-V platforms on which OpenSBI
generic firmwares built by them can run.

To address above, we add Kconfig support for OpenSBI platforms using the
Kconfiglib project which is a standalone kconfig parser.

To try OpenSBI Kconfig support with generic platform, here are few
example commands:
make PLATFORM=generic             <-- builds OpenSBI using "defconfig"
make PLATFORM=generic menuconfig  <-- launches graphical interface for changes

These patches can also be found in the kconfig_v7 branch at:
https://github.com/avpatel/opensbi.git

Changes since v6:
 - Added comments in platform/template/Kconfig for PATCH2
 - Addressed Drew's comments in PATCH16 

Changes since v5:
 - Updated kconfig symbol description in PATCH14
 - Included a typo fix for docs/platform/platform.md in PATCH16
 - Added separate PATCH17 for typo fix in top-level makefile

Changes since v4:
 - Added separate PATCH14 to allow user change generic platform
   version and default name.
 - Fixed libfdt compiler error using LLVM in PATCH12

Changes since v3:
 - Strip down the Kconfiglib sources added by PATCH1
 - Removed extra "." in the top-level Makefile updated by PATCH2

Changes since v2:
 - Use $(FOO) instead of $FOO to access FOO environment variable in
   Kconfig files.
 - Added a new PATCH1 to include Kconfiglib v14.1.0 sources under
   the scripts directory of OpenSBI.

Changes since v1:
 - Fix SPDX license specifier in new Kconfig files
