riscv: Ensure the kernel start address is correctly cast
Cast the kernel start address to the target bit length.
This ensures that we calculate the initrd offset to a valid address for
the architecture.
Steps to reproduce the original problem (reported by Alex):
Build U-Boot for the virt machine for riscv32. Then run it with
$ qemu-system-riscv32 -M virt -kernel u-boot -nographic -initrd <a file>
You can find the initrd address with
U-Boot# fdt addr $fdtcontroladdr
U-Boot# fdt ls /chosen
Then take a peek at that address:
U-Boot# md.b <addr>
and you will see that there is nothing there without this patch. The
reason is that the binary was loaded to a negative address.
