The current riscv_load_fdt() forces fdt_load_addr to be placed at a dram address within 3GB,
but not all platforms have dram_base within 3GB.
This patch adds an exception for dram base not within 3GB,
which will place fdt at dram_end align 16MB.
riscv_setup_rom_reset_vec() also needs to be modified
