Put the name of the stmm images into $STMM_FD so it can be referenced in

Make the 'clean', 'mrproper' & 'distclean' targets match the u-boot
targets of the same name. Also use the 'clean' targets for TFA and the
devicetree-rebasing tree as well as make all clean targets callable when

For U-Boot, all targets are made callable when not configured because
this tool is entirely driven by the U-Boot config.

This tool isn't using $(TARGET) anymore to choose the build platform.
The build configuration is entirely determined by the U-Boot
configuration. Now to use the tool, run "make <target>_defconfig" where
<target> is the name of a file in the u-boot/configs directory.

All platform specific configuration is moved out into separate files so
that the main makefile only contains common code. Choose which files to
include based on the values of u-boot configuration variables. Currently
these four U-Boot variables are used:
   CONFIG_SYS_VENDOR ==> include scripts/vendor-$(CONFIG_SYS_VENDOR).mk
   CONFIG_SYS_SOC ==> include scripts/soc-$(CONFIG_SYS_SOC).mk
   CONFIG_SYS_BOARD ==> include scripts/board-$(CONFIG_SYS_BOARD).mk
   CONFIG_SYS_CONFIG_NAME ==> include scripts/config-$(CONFIG_SYS_CONFIG_NAME).mk

This patch adopts the Linux & U-boot kbuild style top level Makefile
that includes the generated config so that decisions can be made from
the specific config. The core of this change is to pull in the %config
parsing rules for u-boot/Makefile and process them separately from the
main build rules. This allows *config rules to change the U-Boot
configuration, and the import the CONFIG_* values into make so that
TFA_PLAT and other variables can be automatically determined.

Instead of setting the build directory unconditionally (which doesn't
entirely work anyway; U-Boot handles it well, but TFA and DT-rebasing do
not), by default let each project use it's own working directory.
However, if BUILD_BASE is set, then use that to create build directories
for the projects that support it.
