Kévin Redon a634c0efee make peer ERASE more robust ...

adds command 'a' to allow setting/asserting the peer SAM3S ERASE
line on the next command.
this prevents against accidental erase since only the command 'y'
was required, without confirmation.
this could happen not only through accidental user input, but
noise on the serial line (noise would still cause other issues,
but at least now it will not "brick" the device).
now the sequence 'ay' is required, as any other command following
'a' would clear the permission again.

note: since ERASE is only setting a GPIO within this command
parsing function, not accidental function pointer problem calling
'board_exec_dbg_cmd' should cause accidental ERASE since it would
need to be called two times with the exact sequence
