SPCI is renamed as PSA FF-A which stands for Platform Security Architecture Firmware Framework for A class processors. This patch replaces the occurrence of SPCI with PSA FF-A(in documents) or simply FFA(in code). Change-Id: I4ab10adb9ffeef1ff784641dfafd99f515133760 Signed-off-by: J-Alves <joao.alves@arm.com>
