TBB: authenticate BL2 image and certificate
This patch adds support to authenticate the BL2 content certificate
and image using the authentication module in BL1.
The FIP driver has been extended to include the BL2 certificate
UUID.
FVP and Juno ports include the BL2 certificate FIP file
definition.
