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:

Use this when setting the Foundation FVP to use GICv3, but Linux
is expected to use GICv2 emulation mode. In this mode the GIC is
located at the Base location, but the GICv3 is used in GICv2
emulation mode.
