riscv: bootm: Support to boot riscv-linux
riscv-linux should use BBL (Berkeley bootloader) for
loading the Linux kernel.
U-Boot can play as FSBL(first stage bootloader)
to boot BBL and riscv-linux.
In BBL's init_first_hart(), it will pass dtb with a1.
So implement bootm to pass arguments to BBL correctly.
