The Swarm IDE driver uses a release method which is defined in the driver
itself thus potentially oopsable.  The simple fix would be to just leak
the device but this patch goes the full length and moves the entire
handling of the platform device in the platform code and retains only
the platform driver code in drivers/ide/mips/swarm.c.

Rework of SMTC support to make it work with the new clock event system,
allowing "tickless" operation, and to make it compatible with the use of
the "wait_irqoff" idle loop.  The new clocking scheme means that the
previously optional IPI instant replay mechanism is now required, and has
been made more robust.
