Migrate platform ports to the new xlat_tables library

This patch modifies the upstream platform port makefiles to use the new
xlat_tables library files. This patch also makes mmap region setup common
between AArch64 and AArch32 for FVP platform port. The file `fvp_common.c`
is moved from the `plat/arm/board/fvp/aarch64` folder to the parent folder
as it is not specific to AArch64.
