sh: enable sparseirq for highlander and r2d. 

highlander and r2d are the only remaining ones that were blocking
sparseirq being turned on by default, but it turns out that they already
work fine with it by virtue of register_intc_controller(). As such, we
can kill off the dependencies and turn it on by default.

This enables support for sparse irqs. This is useful in general
as most CPUs have a fairly sparse array of IRQ vectors, which
the irq_desc then maps directly on to. Systems with a high
number of off-chip IRQs will want to treat this as
experimental until they have been independently verified.
If you don't know what to do here, say N.
