Fixes for lx2160a build

Some OP-TEE related fixes are needed for the platform to boot correctly
using OP-TEE.
Specifically in TF-A for lx2, the option for parsing header on optee is
not supported.  It expects a binary which can be loaded in memory where
execution can start from.

So add an option to support a single binary creation.

'make flash-usb' will download the firmware to a rk3399 in maskrom mode

AVB is a fine feature, but it isn't actually needed for the purposes of
enabling UEFI secure variables via StMM.

Generalize the config for using U-Boot SPL instead of TF-A BL2. This
simplifies the Rockchip rk3399 support as well as makes it easier to
bring up other boards using CONFIG_SPL

For consistency, and to prevent calling into build targets when doing
config operations, move all the delegate build targets into the else
clause of the $config-targets if/else/endif block.

Cleans up stmm build

Signed-off-by: Grant Likely <grant.likely@arm.com>

edk2/BaseTools is a real directory, so using that as a target means the
target won't get built. Also the stmm target is built from the edk2
tree, so it makes sense to prefix the target with 'edk2-'. Change both
targets to be prefixed with 'edk2-' which should not conflict with the
directory name and can be set up as .PHONY targets.

All u-boot targets were marked as no-dot-config targets, but that breaks
the build because then the script cannot choose how to set environmental
variables like CROSS_COMPILE. Fix by restricting u-boot no-dot-config
targets to %config, %clean and mrproper

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
unconfigured.

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