fvp: Remove call to bl2_get_ns_mem_layout() function
On FVP platforms, for now it is assumed that the normal-world
bootloader is already sitting in its final memory location.
Therefore, BL2 doesn't need to load it and so it doesn't need
to know the extents of the non-trusted DRAM.

AArch64: Remove EL-agnostic TLB helper functions
Also, don't invalidate the TLBs in disable_mmu() function, it's better
to do it in enable_mmu() function just before actually enabling the
MMU.

Unmask SError and Debug exceptions.
Any asynchronous exception caused by the firmware should be handled
in the firmware itself. For this reason, unmask SError exceptions
(and Debug ones as well) on all boot paths. Also route external
abort and SError interrupts to EL3, otherwise they will target EL1.

fvp: Remove unnecessary initializers
Global and static variables are expected to be initialised to zero
by default. This is specified by the C99 standard. This patch
removes some unnecessary initialisations of such variables.
It fixes a compilation warning at the same time:
plat/fvp/bl31_plat_setup.c:82:3: warning: missing braces around
initializer [-Wmissing-braces]
section("tzfw_coherent_mem"))) = {0};
^
plat/fvp/bl31_plat_setup.c:82:3: warning: (near initialization for
‘ns_entry_info[0]’) [-Wmissing-braces]
Note that GCC should not have emitted this warning message in the
first place. The C Standard permits braces to be elided around
subaggregate initializers. See this GCC bug report:

Move generic architectural setup out of blx_plat_arch_setup().
blx_plat_arch_setup() should only perform platform-specific
architectural setup, e.g. enabling the MMU. This patch moves
generic architectural setup code out of blx_plat_arch_setup().
