system: drop the -old-param option

We deprecated the command line option -old-param for the 10.0
release, which allows us to drop it in 10.2.  This option was used to
boot Arm targets with a very old boot protocol using the
'param_struct' ABI.  We only ever needed this on a handful of board
types which have all now been removed from QEMU.
