Pass more -D options to BL*_CPPFLAGS instead of BL*_CFLAGS

Commit d5e97a1d2c79 ("Build: define IMAGE_AT_EL1 or IMAGE_AT_EL3
globally for C files") does not have commit 848a7e8ce1d9 ("Build:
introduce per-BL CPPFLAGS and ASFLAGS") as an ancestor because
they were pulled almost at the same time.

This is a follow-up conversion to be consistent with commit
11a3c5ee7325 ("plat: pass -D option to BL*_CPPFLAGS instead of
BL*_CFLAGS").

With this change, the command line option, IMAGE_AT_EL3, will be
passed to .S files as well.

I remove the definition in include/lib/cpus/aarch64/cpu_macros.S

Otherwise, the following error would happen.

include/lib/cpus/aarch64/cpu_macros.S:29:0: error: "IMAGE_AT_EL3" redefined [-Werror]

cpus: higher performance non-cacheable load forwarding

The CPUACTLR_EL1 register on Cortex-A57 CPUs supports a bit to enable
non-cacheable streaming enhancement. Platforms can set this bit only
if their memory system meets the requirement that cache line fill
requests from the Cortex-A57 processor are atomic.

This patch adds support to enable higher performance non-cacheable load
forwarding for such platforms. Platforms must enable this support by
setting the 'A57_ENABLE_NONCACHEABLE_LOAD_FWD' flag from their
makefiles. This flag is disabled by default.

CPUECTLR_EL1.EXTLLC bit indicates the presense of internal or external

To cater for the platforms(like N1SDP) which has external LLC present
introduce a new build option 'NEOVERSE_N1_EXTERNAL_LLC' which can be
enabled by platform port.

Neoverse N1 Errata Workaround 1542419

Coherent I-cache is causing a prefetch violation where when the core
executes an instruction that has recently been modified, the core might
fetch a stale instruction which violates the ordering of instruction
fetches.

The workaround includes an instruction sequence to implementation
defined registers to trap all EL0 IC IVAU instructions to EL3 and a trap
handler to execute a TLB inner-shareable invalidation to an arbitrary
address followed by a DSB.

Replace __ASSEMBLY__ with compiler-builtin __ASSEMBLER__

NOTE: __ASSEMBLY__ macro is now deprecated in favor of __ASSEMBLER__.

All common C compilers predefine a macro called __ASSEMBLER__ when
preprocessing a .S file. There is no reason for TF-A to define it's own
__ASSEMBLY__ macro for this purpose instead. To unify code with the
export headers (which use __ASSEMBLER__ to avoid one extra dependency),
let's deprecate __ASSEMBLY__ and switch the code base over to the
predefined standard.
