fvp: Remove unnecessary initializers

Browse source 
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:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=53119
