feat(gpt): add support for large GPT mappings
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.
