fix(plat/arm/fvp): make address space configurable

Make FVP physical/virtual address space sizes configurable, with
default at 34-bit (previously hard-coded value).
Maximum tested value is 48-bit, FVP interconnect doesn't yet support
52-bit PA.
Increase MAX_XLAT_TABLE and consequently NS_BL1U_RW_SIZE and
NS_BLU2_LIMIT to accommodate the increased translation tables (based
on 48-bit max PA size).

Custom PA size is passed to build system through the PA_SIZE define.

FVP needs to be configured in a compatible way through the parameters:
* cluster0.PA_SIZE, for each cluster;
* bp.dram_size, setting a memory limit corresponding at least to
  PA_SIZE;
* cci550.addr_width, interconnect address width should match PA_SIZE;
* pci.pci_smmuv3.mmu.SMMU_IDR5, SMMU has to be configured as well if
  present.
