TSP: Print BL32_BASE rather than __RO_START__ 

In debug builds, the TSP prints its image base address and size.
The base address displayed corresponds to the start address of the
read-only section, as defined in the linker script.

This patch changes this to use the BL32_BASE address instead, which is
the same address as __RO_START__ at the moment but has the advantage
to be independent of the linker symbols defined in the linker script
as well as the layout and order of the sections.
