plat/arm: fvp: Do not map GIC region in BL1 and BL2

Browse source 
GIC memory region is not getting used in BL1 and BL2.
Hence avoid its mapping in BL1 and BL2 that freed some
page table entries to map other memory regions in the
future.

Retains mapping of CCN interconnect region in BL1 and BL2
overlapped with the GIC memory region.
