fix(fvp): exclude extend memory map TZC regions

Browse source 
The commit
  1922875233 ("fix(spm-mm): carve out NS buffer TZC400 region")
removes overlaps of ns shared buffer in secure memory region.
Unfortunately, this separation increases 1 region and over maximum
number of TZC programmable regions when they include
extended memory map regions (DRAM3 to DRAM6).

This causes boot failure of StandaloneMm with spmc_el3 && sp_el0 with

    ASSERT: drivers/arm/tzc/tzc400.c:256.

To fix this, like SPM_MM, exclude setting extended memory map regions when
it uses SPMC_AT_EL3 && SPC_AT_EL3_SEL0_SP.
