Compile option `ARM_BOARD_OPTIMISE_MMAP` has been renamed to `ARM_BOARD_OPTIMISE_MEM` because it now applies not only to defines related to the translation tables but to the image size as well. The defines `PLAT_ARM_MAX_BL1_RW_SIZE`, `PLAT_ARM_MAX_BL2_SIZE` and `PLAT_ARM_MAX_BL31_SIZE` have been moved to the file board_arm_def.h. This way, ARM platforms no longer have to set their own values if `ARM_BOARD_OPTIMISE_MEM=0` and they can specify optimized values otherwise. The common sizes have been set to the highest values used for any of the current build configurations. This is needed because in some build configurations some images are running out of space. This way there is a common set of values known to work for all of them and it can be optimized for each particular platform if needed. The space reserved for BL2 when `TRUSTED_BOARD_BOOT=0` has been increased. This is needed because when memory optimisations are disabled the values for Juno of `PLAT_ARM_MMAP_ENTRIES` and `MAX_XLAT_TABLES` are higher. If in this situation the code is compiled in debug mode and with "-O0", the code won't fit. Change-Id: I70a3d8d3a0b0cad1d6b602c01a7ea334776e718e
