Enable MTE support

Enable MTE support by adding memory tag option in Makefile
This option is available only when ARMv8.5-MemTag is implemented

MTE options are added in latest clang and armclang compiler which
support below options:
for clang <version 11.0.0>
1. -march=arm8.5-a+memtag
2. -fsanitize=memtag

for armclang <version 6.12>
1. -march=arm8.5-a+memtag
2. -mmemtag-stack

Set the option SUPPORT_STACK_MEMTAG=yes to enable memory stack tagging.

Add support to pass the nt_fw_config DTB to OP-TEE.

At the moment, OP-TEE has no support to receive a DTB in Secure Memory
so it cannot receive TOS_FW_CONFIG_ID as it is supposed to happen on
any BL32 image. Instead, when OP-TEE is enable as BL32 payload,
NT_FW_CONFIG_ID is passed.

This MUST be reverted as soon as OP-TEE has support for receiving
DTBs from Secure Memory.

Makefile: don't use $(CC) before value is explicit set

Unless specified in the environment, $(CC) expands to some generic

only few lines later.

Move the first use of the $(CC) variable behind the definition to
correct this.

fconf: exclude fconf_dyn_cfg_getter.c from BL1_SOURCES

fconf_dyn_cfg_getter.c calls FCONF_REGISTER_POPULATOR(), which populates
the fconf_populator structure.

However, bl1/bl1.ld.S does not have:

fconf: exclude fconf_dyn_cfg_getter.c from BL1_SOURCES

fconf_dyn_cfg_getter.c calls FCONF_REGISTER_POPULATOR(), which populates
the fconf_populator structure.

However, bl1/bl1.ld.S does not have:

__FCONF_POPULATOR_START__ = .;
KEEP(*(.fconf_populator))
__FCONF_POPULATOR_END__ = .;

So, this is not linked to bl1.elf

We could change either bl1/bl1.lds.S or lib/fconf/fconf.mk to make
them consistent.

I chose to fix up fconf.mk to keep the current behavior.

This is a groundwork to factor out the common code from linker scripts.

Perhaps, this is just a copy-paste mistake of commit 26d1e0c33098
("fconf: necessary modifications to support fconf in BL31 & SP_MIN").
