Since .config has PLATFORM now, it is expected that the PLATFORM= command line
option is no longer necessary as long as a proper .config exists.
This patch implements this expectation. Now the platform to be selected is
determined by the following steps.
1. If PLATFORM= is provided on the command line, the specified value is
used.
2. If there is no PLATFORM= on the command line and PLATFORM is defined in
config.mk, its value is used.
3. If neither PLATFORM= on the command line nor config.mk is available, a
predefined default value is used.
v1 -> v2:
* 'make oldconfig' should not pass CONFIG_xxx to the script since config.mk
can be out-dated.
* Change the default value of PLATFORM to SBL for backward compatibility of
'make all'.

This patch introduces some scripts that takes a Kconfig script and generates
.config or config.h. These scripts are general and can be used by the
hypervisor, dm, tools, etc. as long as proper make targets are added.
Note: Kconfiglib by Ulf Magnusson is ISC licensed.
v4 -> v5:
* Add minimalconfig which creates a defconfig by minimizing a given .config.
v3 -> v4:
* silentoldconfig now properly generate a .config if an old one does not
exist.
v2 -> v3:
* Add license info and the permission notice of Kconfiglib.
* Mention the input Kconfig in the script descriptions.
v1 -> v2:
* Drop kconfiglib.py. The getting started guide will be updated accordingly
and dependency checks will be added to Makefile in the following patches.
