feat(versal): ddr address reservation in dtb at runtime
When the TF-A is placed in DDR memory range, the DDR memory range
needs to be explicitly reserved in the default device tree.
A new build time parameter, XILINX_OF_BOARD_DTB_ADDR, is introduced.
The TF-A will reserve the DDR memory only when a valid DTB address
is provided to XILINX_OF_BOARD_DTB_ADDR during build.
Now the user has options, either manually reserve the desired DDR
address range for TF-A in device tree or let TF-A access and modify
the device tree, to reserve the DDR address range, in runtime using
the build parameter.
