hw/riscv: virt: Convert fdt_load_addr to uint64_t

fdt_load_addr was previously declared as uint32_t which doe not match
with the return type of riscv_compute_fdt_addr().

This patch modifies the fdt_load_addr type from a uint32_t to a uint64_t
to match the riscv_compute_fdt_addr() return type.

This fixes calculating the fdt address when DRAM is mapped to higher
64-bit address.
