riscv: add RISC-V fields to bdinfo command
The firmware invoking main U-Boot uses
* a0 to pass the boot hart
* a1 to pass a device-tree
Let the bdinfo command print this information, e.g.
boot hart = 0x000000000000001b
firmware fdt= 0x0000000087e00000
The firmware fdt field will only be printed if it is non-zero.
