Ahmad Fatoum a3db33fd52 stm32mp1: platform.mk: migrate to implicit rules 
Board Support for the stm32mp1 platform is contained in the device tree,
so if we remove hardcoding of board name from the Makefile, we can build
the intermediary objects once and generate one new tf-a-*.stm32 binary
for every device tree specified. All in one go.

Prepare for this by employing implicit rules.

Trusted Firmware-A

Trusted Firmware-A (TF-A) is a reference implementation of secure world software for Arm A-Profile architectures (Armv8-A and Armv7-A), including an Exception Level 3 (EL3) Secure Monitor. It provides a suitable starting point for productization of secure world boot and runtime firmware, in either the AArch32 or AArch64 execution states.

TF-A implements Arm interface standards, including:

The code is designed to be portable and reusable across hardware platforms and software models that are based on the Armv8-A and Armv7-A architectures.

In collaboration with interested parties, we will continue to enhance TF-A with reference implementations of Arm standards to benefit developers working with Armv7-A and Armv8-A TrustZone technology.

Users are encouraged to do their own security validation, including penetration testing, on any secure world code derived from TF-A.
