bios: Add boot command to be able to boot directly from system memory.

This is useful for un-usual boot sequences where the binaries are not
loaded directly by the BIOS but externally (over a bridge for example).
Example of use:
$litex_sim
$litex_bare_metal_demo --build-path=build/sim
$litex_sim --ram-init=demo.bin
Press Esc during the LiteX boot.
