Enable PIE support so the BL31 firmware can be loaded from anywhere
within the OCRAM (SRAM). How important this is shows the back and forth
of the BL31_BASE address starting with TF-A v2.5. Since then the
BL31_BASE address wasn't stable and choosing the correct combination of
SPL version loadaddress and TF-A version loadaddr was tricky.
For the PIE support we only need to replace the BL31_BASE by the
BL31_START which is a relocatable symbol and to enable it by setting
ENABLE_PIE := 1.
