The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

Wherever possible, replace constructs that match either
generic_handle_irq(irq_find_mapping()) or
generic_handle_irq(irq_linear_revmap()) to a single call to
generic_handle_domain_irq().

The Marvell Armada 7K/8K integrates a secondary interrupt controller
very originally named "PIC". It is connected to the main GIC via a
PPI. Amongst other things, this PIC is used for the ARM PMU.
This commit adds a simple irqchip driver for this interrupt
controller. Since this interrupt controller is not needed early at boot
time, we make the driver a proper platform driver rather than use the
IRQCHIP_DECLARE() mechanism.
