fix(fvp): add DRAM memory regions that linux kernel can share

The memory regions that Linux kernel can share including TX/RX buffers
encompass the entire DRAM. Update it accordingly. Without this,
when the Linux kernel call FFA_RXTX_MAP, it fails sometime and the
below error from the secure world appears:

  |  ERROR: arch_other_world_vm_configure_rxtx_map: send page is invalid
  | 		(expected 0x87, got 0x7c)
