Jayanth Dodderi Chidanand 820371b130 fix(amu): add default value for ENABLE_FEAT_FGT and ENABLE_FEAT_ECV flags 
ENABLE_FEAT_FGT and ENABLE_FEAT_ECV macros are used to access
HDFGRTR_EL2 and CNTPOFF_EL2 registers respectively. These flags are set
to true for v8.6 and upwards and are not handled explicitly for lower
architecture versions.

This patch adds definitive default value to these build macros, so that
for v8.5 and below, they are not overridden and set to true by the gcc.

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.
