The current defconfigs are BIOS-specific which makes it difficult to maintain
multiple defconfigs for boards running the same BIOS.
This patch re-organizes the defconfigs to be board-specific. A command line
option BOARD is introduced to specify a board on which the current build targets
at. The original PLATFORM is kept for backward compatibility which redirects to
apl-mrb and nuc6cayh for sbl and uefi, respectively.
The getting started guide is also updated accordingly.
v1 -> v2:
* Rewrite 'up2' to 'UP2'.

Without any command under the .config target, config.mk will not be remade in
the same execution of make after oldconfig changes .config. This can result to
inconsistency between .config and the built image right after .config is
changed.

It is faster to check the existance of a certain library by trying importing
that library, instead of invoking pip3 for a complete list of installed
libraries. Time of the check can be significantly reduced.

This patch introduces a configuration symbol RELEASE for managing debug/release
build in a similar way to how we manage PLATFORM.
Note:
1. 'make defconfig RELEASE=1' will still use the CONFIG_RELEASE defined in the
default configuration. The 'RELEASE=1' option has no effect in this case.
2. 'make RELEASE=1' is backward-compatible and enforces a release version to be
built.
v1 -> v2:
* Pass RELEASE instead of CONFIG_RELEASE to silentoldconfig.py to avoid
unintended overriding of the value.

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 enables 'make menuconfig' leveraging the menuconfig.py in kconfiglib,
which shows a TUI for modifying the current configurations.
Menuconfig.py is python3 only, and thus the existence of 'python3' instead of
'python' is checked and python3 is used to run all the scripts.

The current implementation of the check_dep_* macros always append the
prerequisite checking target to BUILD_DEPS, but there are some cases when some
prerequisites are only necessary for some specific targets instead of general
builds.
This patch adds a second parameter to the check_dep_* macros specifying which
variable the generated target should be appended to.

Makefile takes all double quotes in variable definitions literally. Thus with
the following definition:
FOO := "a"
expanding FOO in a file path results the following (which is invalid):
SRC += a/b/${FOO}.c --> SRC += a/b/"a".c
To avoid such issues, this patch drops the double quotes at the beginning and
end of the definition of symbols with string type.

Before checking any given target, make has an additional phase to check if any
included makefile should be updated. This patch enforces running oldconfig in
this phase to update .config and config.mk (if necessary). This ensures that
make gets the correct configurations when executing the given target.

CFLAGS for the configuration data.
Also make sure that all configuration data have the 'CONFIG_' prefix.
v4 -> v5:

* Add '-include config.h' to hypervisor/bsp/uefi/efi/Makefile.
* Update comments mentioning bsp_cfg.h.
v2 -> v3:
* Include config.h on the command line instead of in any header or source to
avoid including config.h multiple times.
* Add config.h as an additional dependency for source compilation.

This patch implements the following targets as an includable .mk to the make
system of the hypervisor.
make defconfig PLATFORM=xx:
force (re)generating the default configuration for xx
make oldconfig PLATFORM=xx:
generate a configuration for platform xx based on .config if available
make minimalconfig
save a minimized .config to defconfig
The default target (make all) will generate a default configuration if no
.config is available.
The values defined in .config are available in the toplevel Makefile after
kconfig/kconfig.mk is included.
v4 -> v5:
* Add minimalconfig for generating default configs.
v3 -> v4:
* No changes.
v2 -> v3:
* "make defconfig" now correctly overwrite an existing .config.
* Add short descriptions on where each target is supposed to be used.
v1 -> v2:
* Add proper dependency checks in the Makefile of hypervisor.
