This patch adds support for large GPT mappings using Contiguous descriptors. The maximum size of supported contiguous block in MB is defined in RME_GPT_MAX_BLOCK build parameter and takes values 0, 2, 32 and 512 and by default set to 2 in make_helpers/defaults.mk. Setting RME_GPT_MAX_BLOCK value to 0 disables use of Contiguous descriptors. Function gpt_tlbi_by_pa_ll() and its declaration are removed from lib/aarch64/misc_helpers.S and include/arch/aarch64/arch_helpers.h, because the GPT library now uses tlbirpalos_xxx() functions.
