Pull up following revision(s) (requested by bjh21 in ticket #10703):
        sys/arch/acorn32/podulebus/simide.c: revision 1.24
PR 23783: the correct number of elements to insert into cmd_iohs is WDC_NREG,
not DRIVE_REGISTERS_SPACE.  The latter is much bigger and causes a buffer
overrun and panic.  Patch supplied by Mike Pumford.
