FWU: Add Generic BL2U FWU image support in BL2
The Firmware Update (FWU) feature needs support for an optional
secure world image, BL2U, to allow additional secure world
initialization required by FWU, for example DDR initialization.
This patch adds generic framework support to create BL2U.
NOTE: A platform makefile must supply additional `BL2U_SOURCES`
to build the bl2u target. A subsequent patch adds bl2u
support for ARM platforms.
